- Enable arranging only when the Screen Options tab is open.
- Prevent accidental/unintended dragging. Seen it happen mostly on laptops when using the mousepad/trackpad.
- Improve discoverability and usefulness by always showing the "drop zones" outline when postboxes are draggable/arrangeable.
- Add some (brief) explanation to the Screen Options tab helping the user understand what options are available and how to change them. This is especially helpful for screen reader users to give an idea how to use the screen options and what to expect.
- Fix/enhance some of the code in `postbox.js` and make it coding standards compliant.

So far, it has been possible to rearrange into a new order the post boxes (also known as "widgets" on the Dashboard and "meta boxes" on the Edit post page) only by using a pointing device, for example a mouse.
This change adds new controls and functionality to allow the boxes to be rearranged also with the keyboard. Additionally, audible messages are sent to the admin ARIA live region to notify screen reader users of the reorder action result.

Visible `<label>` elements benefit all users. The `placeholder` attribute should not be used as a replacement for visible labels.
Instead, it's supposed to be used only for a short hint to aid users with data entry e.g. a sample value or a brief description of the expected format.
Screen readers may not announce a `placeholder` attribute at all. Other users may suffer from the lack of a visible label and a placeholder used as replacement, for example:
- users with cognitive disabilities may have trouble remembering what the filled field does
- speech recognition users cannot see the name they can speak to set focus on the field
- low-vision users with high text-size may not be able to see the whole placeholder even when it's visible, if its value is clipped by the edge of the input

Depending on the amount of meta boxes and the layout settings under Screen Options, sortable meta boxes may not be actually sortable.
In these cases, jQuery UI sortable needs to be disabled and the user interface shouldn't use a CSS `cursor: move`.
The use of consistent and relevant cursors may be important for users who have a cognitive disability, since cursors give a visual clue as to an element's functionality. Using the move cursor for elements which cannot be moved may be confusing or counter-intuitive for users.

In many a strange and curious file of forgotten lore—
While I pondered, blaming Nacin, my notifications suddenly awakened,
As of someone quietly DMing;—DMing me, I can’t ignore.
“’Tis some contributor,” I muttered, “DMing me an idea or four—
Only this and nothing more.”
Ah, distinctly I remember, at WordCamp US, last December;
A mad proposal nearly laid me—down out cold—upon the floor.
Curious, I listened closely;—to a plan I agreed with, mostly—
A way to make our JavaScript—JavaScript which was a chore—
Maintainable, extendable, for the future, is what I saw.
Guten-ready for evermore.
Open here I switch to Slack, when, with many a patch and hack,
In there stepped Omar, a JavaScript developer hardcore;
Pronouncing all the changes fit; ready now to be commit;
“There’s nothing else for us to do,” DMing me, “It’s done!” he swore—
“No longer random guessing at which file need next be explored—
Let’s move on, we’re all aboard.”
Moved all together, grouped and managed, in folders all is packaged,
The code had all been cleaned and tidied, important parts moved to the fore,
“Though this change be useful here,” I said, “it is too large, I fear,
We couldn’t manage such a patch, we’ve done nothing like this before—
Tell me where doth go this change, change to make our codebase soar!”
Quoth Omar, “In WordPress Core.”

- also, removes a few textdomain leftovers, see `better-code-editing` and `default`

* Invalidate PHP opcache after file is updated to ensure `include` will ''include'' the written changes.
* Define `WP_ADMIN` when activating plugin in sandbox so plugin code targeting admin will be loaded.
* Do actions that get triggered when loading the admin to ensure plugin code runs that could cause errors on plugin editor screen (and lock out access).
* Fix ability to re-activate a plugin after editing a PHP file other than the main plugin file, and ensure PHP fatal error will be displayed in such cases.
* Consolidate duplicated code into `plugin_sandbox_scrape()` and re-use in `activate_plugin()`.
* Show an error notice instead of a success notice when a file is updated but a plugin was deactivated due to a fatal error.
* Update style of warning when editing an active plugin to be styled as an actual warning notice.

* Code editor is integrated into the Theme/Plugin Editor, Additional CSS in Customizer, and Custom HTML widget. Code editor is not yet integrated into the post editor, and it may not be until accessibility concerns are addressed.
* The CodeMirror component in the Custom HTML widget is integrated in a similar way to TinyMCE being integrated into the Text widget, adopting the same approach for integrating dynamic JavaScript-initialized fields.
* Linting is performed for JS, CSS, HTML, and JSON via JSHint, CSSLint, HTMLHint, and JSONLint respectively. Linting is not yet supported for PHP.
* When user lacks `unfiltered_html` the capability, the Custom HTML widget will report any Kses-invalid elements and attributes as errors via a custom Kses rule for HTMLHint.
* When linting errors are detected, the user will be prevented from saving the code until the errors are fixed, reducing instances of broken websites.
* The placeholder value is removed from Custom CSS in favor of a fleshed-out section description which now auto-expands when the CSS field is empty. See #39892.
* The CodeMirror library is included as `wp.CodeMirror` to prevent conflicts with any existing `CodeMirror` global.
* An `wp.codeEditor.initialize()` API in JS is provided to convert a `textarea` into CodeMirror, with a `wp_enqueue_code_editor()` function in PHP to manage enqueueing the assets and settings needed to edit a given type of code.
* A user preference is added to manage whether or not "syntax highlighting" is enabled. The feature is opt-out, being enabled by default.
* Allowed file extensions in the theme and plugin editors have been updated to include formats which CodeMirror has modes for: `conf`, `css`, `diff`, `patch`, `html`, `htm`, `http`, `js`, `json`, `jsx`, `less`, `md`, `php`, `phtml`, `php3`, `php4`, `php5`, `php7`, `phps`, `scss`, `sass`, `sh`, `bash`, `sql`, `svg`, `xml`, `yml`, `yaml`, `txt`.

The Plugin details modal custom implementation in the Plugins page conflicts with
other Thickbox instances added by plugins. Thickbox shows its age and has been
modified over time to suit core needs. However, WordPress should do its best to
not create conflicts with the native Thickbox styles and functionalities. Plugin
authors should be able to use `add_thickbox()` in any admin page as documented,
without having to worry about potential errors.
- fixes a JavaScript error when closing a native Thickbox modal in the Plugins page
- avoids to override the native Thickbox modal styles
- uses a CSS class to target the Plugin details modal and remove a pile of overqualified CSS selectors

WordPress no longer supports many old old browsers: https://make.wordpress.org/core/2017/04/23/target-browser-coverage/
This also removes alot of no longer necessary CSS. It served us well, but we are never getting back together with IE8,9,10.
So, in the (paraphrased) words of Taylor Swift:
I remember when we dropped support the first time
Saying, "This is it, I've had enough, " 'cause like
We hadn't seen many users in a month
When you said you needed flexbox. (What?)
Then you postMessage again and say
"IE8, I miss you and I swear I'm gonna change, trust me."
Remember how that lasted for a day?
I say, "I hate the box model, " we break up, you call me, "I love css-grids."
Ooh, we called it off again last night
But ooh, this time I'm telling you, I'm telling you
We are never ever ever supporting IE 8,9,10,
We are never ever ever supporting IE 8,9,10,
You go talk to EDGE, talk to my FIREFOX, talk to CHROME
But we are never ever ever ever getting back together
Like, ever...

Links used as UI controls that behave like buttons, should be buttons.
- changes the widgets "toggle", "Delete", and "Close" links to buttons
- uses `aria-expanded` to announce the state of the toggle buttons
- increases a bit the clickable area of the toggle
- ensures the "circular focus" doesn't get cut-off in some browsers by centering the toggle arrows
- uses a `<span>` element with an `aria-hidden` attribute to hide CSS generated font icons from assistive technologies
- standardizes on `.toggle-indicator:before` rather than `:after`
- changes two `#f00` reds in `#dc3232`, see #35622Fixes#31476.
