* Prevent loading `wp-embed` script unconditionally on every page in favor of conditionally enqueueing when a post embed is detected. The `wp-embed` script is also explicitly marked as being in the footer group. Sites which currently disable post embed scripts from being enqueued via `remove_action( 'wp_head', 'wp_oembed_add_host_js' )` will continue to do so.
* Send a `ready` message from the host page to each post embed window in case the `iframe` loads before the `wp-embed` script does. When the `ready` message is received by the post embed window, it sends the same `height` message as it sends when it loads.
* Eliminate use of `grunt-include` to inject emoji script and the post embed script. Instead obtain the script contents via `file_get_contents()` (as is done elsewhere in core) and utilize `wp_print_inline_script_tag()`/`wp_get_inline_script_tag()` to construct out the script. This simplifies the logic and allows the running of src without `SCRIPT_DEBUG` enabled.
* For the embed code that users are provided to copy for embedding outside of WP, add the `secret` on the `blockquote` and `iframe`. This ensures the `blockquote` will be hidden when the `iframe` loads. The embed code in question is accessed here via `get_post_embed_html()`.

Patches occasionally come in on generated files. We should be kind to new contributors and give them a hint that these files are auto-generated.
This is a follow-up to [41271], which added the banner to minified CSS files.

In the data sent to us from the embedded iframe by postMessage(), the secret value is being used directly in a document.querySelectorAll() call without first being validated or escaped.
In theory, this could lead to some broken embeds.

Older versions of WordPress will convert those `&` characters to `&`, which makes for some non-functional JS. If folks are running an older release, let's not make their lives more difficult than it already is.

Sometimes, embedded sites might suffer from less than 100% uptime. Instead of leaving the embedding site with a big blank space where the embed should be, let's fall back to a link to the embedded post, so there's at least some context for the post.
