	/**
	 * Filters the `css` (`post_content`) and `preprocessed` (`post_content_filtered`) args for a `custom_css` post being updated.
	 *
	 * This filter can be used by plugin that offer CSS pre-processors, to store the original
	 * pre-processed CSS in `post_content_filtered` and then store processed CSS in `post_content`.
	 * When used in this way, the `post_content_filtered` should be supplied as the setting value
	 * instead of `post_content` via a the `customize_value_custom_css` filter, for example:
	 *
	 * <code>
	 * add_filter( 'customize_value_custom_css', function( $value, $setting ) {
	 *     $post = wp_get_custom_css_post( $setting->stylesheet );
	 *     if ( $post && ! empty( $post->post_content_filtered ) ) {
	 *         $css = $post->post_content_filtered;
	 *     }
	 *     return $css;
	 * }, 10, 2 );
	 * </code>

	 * }
