iOS disables this feature under the hood, but it also distorts the images – unlike other mobile devices that don't support it. So this adds a check for both `background-attachment: fixed` support or whether it’s an iOS device - passing it adds the class `background-fixed` which is used to add the proper styles.
It also lowers the media query so the parallax-like style is present on a wider range of screens since this bug can be better targeted and avoided. In this way, screens that aren't the offending devices aren't punished merely based on screen size.

The `sizes` attribute was calculated incorrectly, resulting in the browser downloading the wrong resource. This filters the attribute to correct that.
Before the filter, the `img` contained:
`sizes="(max-width: 767px) 89vw, (max-width: 1000px) 54vw, (max-width: 1071px) 543px, 580px"`
And after:
`sizes="100vw"`

Some widgets that require more configuration are not included, such as RSS and Custom Menu. Tag Cloud is also not included because fresh sites do not have any tags to display.
Also adds a search widget to a Twenty Seventeen footer widget area.

* 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.

* Hides the `.custom-header-image`div in CSS when an image or video haven't been set so preview changes are smoother.

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.

* Adds unique IDs for title and desc for accessible implementation options.
* Removes absolute path in the Customizer. It didn't work in Internet Explorer, and the original bug is fixed in #30028.

The combination of font-size and weight for post navigation made lower case "i"s illegible in some cases. Using `15px` seemed to be the best choice all around. Also adjusts the spacing around the arrows a bit, since they touch the text on small screen sizes.

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()`.

This also reduces the number of browsers detected and patched with this fix. Most modern browsers have patched this common bug, where an anchor link does not move focus when clicked. Twenty Seventeen will only worry about older versions of Internet Explorer in this regard.

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.
