FSE navigation (WP 5.9 beta): aria-labels are not sanitized

FSE navigation items containing HTML (like inline images) in nav labels are not sanitized and break the submenu layout.

An issue and a PR have been submitted in the Gutenberg repo last week (see link). Would it be possible to review the changes and merge to trunk if applicable?

Thanks in advance.
