* Attempts to refer to the inner-block wrapping element by its class attribute.
*
* When examining a block's inner content, if a block has inner blocks, then
* 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( '<ul class="list-wrapper is-unordered">', null, '</ul>' );
*
* // After rendering, the initial contents may have been modified by other renderers or filters.
* $block_content = <<<HTML
* <figure>
* <ul class="annotated-list list-wrapper is-unordered">
* <li>Code</li>
* </ul><figcaption>It's a list!</figcaption>
* </figure>
* HTML;
*
* Although it is possible that the original block-wrapper classes are changed in $block_content
* from how they appear in $block['innerContent'], it's likely that the original class attributes
* are still present in the wrapper as they are in this example. Frequently, additional classes
* will also be present; rarely should classes be removed.
*
* @todo Find a better way to match the first inner block. If it's possible to identify where the
* first inner block starts, then it will be possible to find the last tag before it starts
* and then that tag, if an opening tag, can be solidly identified as a wrapping element.
* Can some unique value or class or ID be added to the inner blocks when they process
* so that they can be extracted here safely without guessing? Can the block rendering function
* return information about where the rendered inner blocks start?
*
