* the first content item will likely be a text (HTML) chunk immediately
* preceding the inner blocks. The last HTML tag in that chunk would then be
* an opening tag for an element that wraps the inner blocks.
*
* There's no reliable way to associate this wrapper in $block_content because
* it may have changed during the rendering pipeline (as inner contents is
* provided before rendering) and through previous filters. In many cases,
* however, the `class` attribute will be a good-enough identifier, so this
* code finds the last tag in that chunk and stores the `class` attribute
* so that it can be used later when working through the rendered block output
* to identify the wrapping element and add the remaining class names to it.
*
* It's also possible that no inner block wrapper even exists. If that's the
* case this code could apply the class names to an invalid element.
*
* Example:
*
* $block['innerBlocks'] = array( $list_item );
* $block['innerContent'] = array( '
