fe346c1464 Comments: Prevent AYS prompt when replying to a comment and nothing has been entered.
When replying to a comment and nothing has yet been entered for the reply content, clicking "Reply" or "Quick Edit" on another comment presents the "Are you sure..." prompt indicating there are unsaved changes in the reply content.  However, if nothing is entered, this prompt should not be displayed.

This change implements a new check to determine if any text has been entered by the user before deciding to show the "Are you sure..." prompt.

92a1067f1d Comments: Disable "close on escape" for inline replies when using an IME.
When using an Input Method Editor(IME), pressing escape to perform actions in the IME is common.  However, if this was done while replying to a comment, the "close on escape" feature was also triggered which cleared the current textarea and closed it.

This change checks if an IME is in use by binding the `compositionstart` event to the reply text box and setting a flag if it's triggered.  The "close on escape" feature will now only be triggered if this new flag is not set after typing a reply.

To be able to disable jQuery Migrate as step 3 of updating the jQuery version shipped with WordPress, all `JQMIGRATE` warnings in the browser console will have to be addressed.

This includes many minor adjustments to a wide array of core files.

e901bc4c2b Accessibility: Improve the Comments and Privacy count text.
- standardizes the Comment count string to `%s Comment in moderation', '%s Comments in moderation` so it can be bulk-updated
- adds the string as visually hidden text in the admin menu 
- introduces an `updateInModerationText` JS simple function, responsible to correctly update all the related text using the data from the AJAX response
- adds a visually hidden text "1 Privacy Policy update" to the Privacy menu items count
- adds/improves translators comments

Changes that apply to all the count bubbles (Updates, plugins, etc.)
- makes the bubbles and their text slightly bigger
- improves the active menu item bubble contrast by changing the background color to red (option 2 in the screenshot attached in a previous comment)

6fe48278ea Accessibility: Comments: Improve links and buttons semantics and interaction.
With the exception of the "Edit" link, the "row actions" controls in the Comments table behave differently depending if JavaScript support is on or off.
When JavaScript support is off, they behave like links. When JavaScript support is on, they behave like buttons and they need to be buttons or have an ARIA `role="button"` added via JavaScript.

Lastly, the buttons in the Reply/Quick Edit form and the "Add Comment" in the edit post page meta box need to be buttons.

bdbaccce37 General: Explicitly assigns all JS globals to the window.

bde558be2f Docs: Add file doc @output annotations.
These annotations make it clear to the reader of a JavaScript source
where the build process outputs to. These annotations can later be
integrated in a webpack configuration. This way there is one source of
truth.

The `build` folder is omitted from the paths, because a single JS file
shouldn't not be responsible of knowing where outputs in general will
end up at. A file only knows its output location relative to the
project.

2e2223ae74 Comments List Table:
* In a view that initially has comments, but they get removed due to user actions: show the `No Items` row instead of bombing out and showing nothing (which looks broken)
* To accomplish this, in `WP_Comments_List_Table::display()`: call `->display_rows_or_placeholder()` instead of `->display()`
* Listen for the end of row `.fadeOut()`s if necessary using jQuery Promises

Fixes #11200.

3ac1a19529 Spinners: Toggle a class instead of show/hide.
Toggling spinners also now uses visibility instead of display, so that the space is always reserved and nothing moves around unexpectedly.
