Message:

HTML API: Report breadcrumbs properly when visiting virtual nodes.

When [58304] introduced the abililty to visit virtual nodes in the HTML document,
those being the nodes which are implied by the HTML but no explicitly present in
the raw text, a bug was introduced in the get_breadcrumbs() method because it
wasn't updated to be aware of the virtual nodes. Therefore it would report the
wrong breadcrumbs for virtual nodes. Since the new get_depth() method is based
on the same logic it was also broken for virtual nodes.

In this patch, the breadcrumbs have been updated to account for the virtual nodes
and the depth method has been updated to rely on the fixed breadcrumb logic.

Developed in ​https://github.com/WordPress/wordpress-develop/pull/6914
Discussed in https://core.trac.wordpress.org/ticket/61348

Follow-up to [58304].
