* Use `postMessage` transport for header image settings by default when video headers are supported, and thus `the_custom_header_markup()` will necessarily be used (and thus a selective refresh partial will be available).
* Ensure that `the_custom_header_markup()` always outputs a container element in the customizer preview even if the header is empty.
* Ensure that edit shortcut appearing for custom header does not get positioned off-screen.

* Toggles `has-header-image` body class in Customizer preview whenever images or videos are added or removed.
* Hides the `.custom-header-image`div in CSS when an image or video haven't been set so preview changes are smoother.
* Also fixes the main issues in #38391 – making the preview match.

IE9 doesn't understands `vh ` (vertical height) when inside of an `iframe`. Normally IE9 will understand `vh` as the vertical height relative to the viewport, but in an `iframe`, IE9 thinks the vertical height is relative to the size of the whole page. So this fixes that when the site is viewed in the Customizer preview – an `iframe`.

The CSS property `background-attachment: fixed` is disabled in some mobile browsers for performance reasons. So here, the fix increases the breakpoint where the `background-attachment: fixed` is applied to the front page images. Doing this removes the fixed backgrounds and the issue from all smaller screens, but the downside is that it also removes the fixed backgrounds from smaller laptops. It's also possible future devices could fall into this breakpoint, but this seems to be the most practical solution.

TwentySeventeen attempts to highlight media found in post content by using `get_media_embedded_in_content()` to extract videos from the content and display their HTML differently. However, the HTML being generated by the playlist shortcode relies on JavaScript to update the video element with the markup needed to display the playlist properly. The `get_media_embedded_in_content()` function wasn't designed to handle this use case.
The patch looks for the presence of `wp-playlist-script` in the content and shows the standard content rather than trying to pluck the media elements from the content using `get_media_embedded_in_content()`.

In -r39124, some additional issues were introduced:
* The 'overflow: hidden' on the `.site-header;` was added to prevent a side-scrolling issue, but it ended up cutting off the menu. It looks like the cause of the side-scroll was related to how the scroll down icon was rotated, so it's addressed by rotating the icon and not the `<a>`.
* Also, `min-height` doesn't play well with `display: table;` in Firefox. So it's addressed with just `height`.

In [38985], we used jQuery to trigger a custom event once a video
handler has completed so themes, like Twenty Fourteen, can execute
their own adjustments after the header video has loaded.
This replaces the jQuery `trigger()` method with a native event and
updates Twenty Fourteen accordingly.

A theme can opt-in for tailored starter content to apply to the customizer when previewing the theme on a fresh install, when `fresh_site` is at its initial `1` value. Starter content is staged in the customizer and does not go live unless the changes are published. Initial starter content is added to Twenty Seventeen.
* The `fresh_site` flag is cleared when a published post or page is saved, when widgets are modified, or when the customizer state is saved.
* Starter content is registered via `starter-content` theme support, where the argument is an array containing `widgets`, `posts`, `nav_menus`, `options`, and `theme_mods`. Posts/pages in starter content are created with the `auto-draft` status, re-using the page/post stubs feature added to nav menus and the static front page controls.
* A `get_theme_starter_content` filter allows for plugins to extend a theme's starter content.
* Starter content in themes can/should re-use existing starter content items in core by using named placeholders.
* Import theme starter content into customized state when fresh site.
* Prevent original_title differences from causing refreshes if title is present.
* Ensure nav menu item url is set according to object when previewing.
* Make sure initial saved state is false if there are dirty settings without an existing changeset.
* Ensure dirty settings are cleaned upon changeset publishing.

* Only show the colorscheme_hue control when there's a custom color scheme.
* Update preview JS handling for revised front page section handling, see below.
* Remove all references to "Theme Customizer" in code comments. It hasn't been called that since before 4.0.
* Clarify the purpose of the JS files by updated the code comments in the file headers.
* Improve code readability.
* Make the arbitrary number of front page sections filterable, for UI registration and output.
* Rename twentyseventeen_sanitize_layout to twentyseventeen_sanitize_page_layout to be clearer about what it sanitizes in case child themes or plugins consider reusing it.
* Rename page_options setting/control to page_layout as that's more reflective of what that option does; and again, helps for potential extensions.
* Make the page layout option contextual to pages and the sidebar being inactive, as the option only applies when there is no sidebar (per its description).
* Condense options into a single section.
* Add selective refresh for front page sections.
* Locate active_callback functions within customizer.php so that they're easier to find when editing customizer registrations, similarly to sanitize callbacks.
* Adjust the styling for placeholders for panels that aren't active.

This adds the ability for themes to add support for videos in custom headers
by passing `'video' => true` as an argument when adding theme support for
custom headers.
Custom video headers are managed through the “Header Visuals” (i.e. “Header Image”)
panel in the Customizer where you can select a video from the media library or set a
URL to an external video (YouTube for now) for use in custom headers.
This introduces several new functions:
`has_header_video()` – Check whether a header video is set or not.
`get_header_video_url()` – Retrieve header video URL for custom header.
`the_header_video_url()` – Display header video URL.
`get_header_video_settings()` – Retrieve header video settings.
`has_custom_header()` – Check whether a custom header is set or not.
`get_custom_header_markup()` – Retrieve the markup for a custom header.
`the_custom_header_markup()` – Print the markup for a custom header.
And a new file, `wp-includes/js/wp-custom-header.js` that handles loading videos
in custom headers.
This also enables video headers in the Twenty Seventeen and Twenty Fourteen themes.
