Users need to be able to highlight text in the WYSIWYG editor and wrap it in a lang="mi" from a menu item.
The current Language menu item, doesn't contain te reo MΔori as an option.
We want to make sure that custom language 'lang="mi"' is on the allowed list for all text formats.
See https://www.drupal.org/project/drupal/issues/3273986 β¨ Third option for the CKEditor 5 "Language" button: `site_configured` (in addition to `un` and `all`) RTBC
Merging Drupal 10.2 will include the fixes to the Language widget menu item which allows the site's configured languages to be chosen.
Add: to the Source Editing option.
Note: We'll also need the embedded content fork's fix that's still to be merged, in order to more easily add the Language widget to the menu bar.
Closed: won't fix
10.0

This will be added to specific projects that require the feature rather than in our starter kit.
