    panel: Restrict app menu width
    
    Window titles aren't restricted in length, so the menu may end up unwieldily
    width. Commit 0bec76b6ee therefore limited the app context menus, but that
    got accidentally dropped in commit 0ded0dbfd5. Add back the limitation and
    extend it to the new app menu as well.
