	 * Note that the script must be placed after the <blockquote> and <iframe> due to a regexp parsing issue in
	 * `wp_filter_oembed_result()`. Because of the regex pattern starts with `|(<blockquote>.*?</blockquote>)?.*|`
	 * wherein the <blockquote> is marked as being optional, if it is not at the beginning of the string then the group
	 * will fail to match and everything will be matched by `.*` and not included in the group. This regex issue goes
	 * back to WordPress 4.4, so in order to not break older installs this script must come at the end.
	$output .= wp_get_inline_script_tag(

	 * Filters the embed HTML output for a given post.
