* Ensure that starter content can apply from theme B after previewing starter content in theme A.
* Introduce new `starter_content` flag in changeset setting params which is used to capture whether a value is starter content and thus can be overridden.
* Create changeset up-front with `starter_content` flags instead of waiting for `AUTOSAVE_INTERVAL`.
* Eliminate instantiation of settings for widget instances in favor of directly calling `sanitize_widget_js_instance`. This eliminates issues with looking for widgets before they are registered.
* Ensure that non-placeholders (inline arrays instead of string references) can be supplied in starter content.
* Re-use auto-draft posts as starter content across theme switches.
* Introduce `starter_content` param for `WP_Customize_Manager::save_changeset_post()` which is `false` except when starter content is being loaded on a `fresh_site`.

Adds a callback for determining when video headers should be displayed in themes supporting custom headers. By default, video headers are only displayed on the front page of a site.
Theme authors may set a custom callback by passing `'video-active-callback' => 'mytheme_video_active_callback'` as an argument. The default callback is `is_front_page()`.
This introduces the new function `is_header_video_active()` - returns `true` on pages that should display video headers. The return value can be filtered using the new filter of the same name.

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.

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()`.
