I found a couple of new problems with the 'Select InnputMethod' menu:
   1. A menu item cannot be selected with keyboard even if you can go through menu items with arrow keys. I.e. SPACE or ENTER don't make an action.
   2. If mouse cursor is above the menu and then it is moved outside the menu, the menu loses the focus and cannot be handled with keyboard.
