When `home` and `siteurl` are different, the customizer preview iframe will be blank in Chrome and Safari, due to their `X-Frame-Options` implementation quirks.
Changing this to `SAMEORIGIN` and adding the `frame-ancestors` Content Security Policy gives the correct behaviour.
Props fullyint.

From the `WordPress.NamingConventions.ValidVariableName` sniff, this commit fixes/whitelists all `NotSnakeCaseMemberVar`, `MemberNotSnakeCase`, and `StringNotSnakeCase` violations. It also fixes a handful of the `NotSnakeCase` violations.

Calling `register_rest_route()` too early in the loading process has the potential to cause some unintentional problems and pitfalls. Because `register_rest_route()` calls `rest_get_server()` (which creates the `WP_REST_Server` instance), calling the function directly and/or before `rest_api_init` should be discouraged.
For example, if `register_rest_route ()` is called on `init`, the REST API server instance is set up (and all functions added to `rest_api_init` and other related hooks are invoked), even though the current request may not be a REST request. Also, if `register_rest_route()` is called even earlier (say, in an `mu-plugin` file), required endpoints may be missing since normal plugins have not yet been loaded and have not had a chance to register their own action hooks.
This adds a `_doing_it_wrong()` notice the first time `register_rest_route()` is called before `rest_api_init` in a request to encourage best practices for registering REST API routes.

Both `wp_encode_emoji()` and `wp_staticize_emoji()` perform a PHP version check when deciding how to apply their behaviour, but this check only needs to happen once, rather than every time in their internal looks.
Moving the check outside of the loop reduces processing time by 50%.

At the start of `render_block()`, the `pre_render_block` filter allows the function to be short-circuited, and the `render_block_data` filter is applied to the `$block` parameter before it's processed.

WordPress has historically often used code like `preg_split( '/[\s,]+/', $var )` to parse a string of comma-separated values into an array. However, this approach was causing an empty string to not be parsed into an empty array as expected, but rather into an array with the empty string as its sole element.
This was among other areas causing problems in the REST API where passing an empty request parameter could cause that request to fail because, instead of it being ignored, that parameter would be compared against the valid values for it, which typically do not include an empty string.

Introduces in core new focus styles dedicated to Windows High Contrast mode. The
new styles use a transparent CSS outline as already explored in the Block Editor.
This first part covers some of the main user interface controls like buttons, links,
and media views elements. Other parts will be addressed in the next future.

Sometimes, Safari and VoiceOver read out the text hidden with `screen-reader-text`
in a wrong order. While there's no known, full, solution, it is possible to make
them respect the correct order reliably at least within buttons.

The `keyup` event was used to provide support for IE8, where which doesn't support the `input` event. As we dropped IE8 support some time ago, this was simply adding unnecessary complexity and double-event triggers.

Defining `WP_TESTS_SKIP_INSTALL=1` when running tests will skip the install step. While this shouldn't be used for full test runs, it's useful for saving time when running small groups of tests.
