Summary

As the dialog for language versions has any focus trap, keyboard users will "leave" the dialog and continues to tab on main page, when she should stay on the dialog until it is closed

Details

Add a script to prevent keyboard users to leave the dialog before closing it

Shouldn't the <dialog /> element take care of that when it's in modal-mode? That automatically makes the document inert (except for the dialog).

Has this issue already been completed? Focus trap appears to be working correctly for me

Closing this issue as it seems to work as expected.
