Thank you for the report, I can reproduce. This is deep recursion in FocusController::nextFocusableElementWithinScope that results in exhausting stack space.

@Joey: Are you aware of an OS version where this worked as expected? This would help narrow the search for the root cause, but no problem if you are not sure.
