    Bug 941567 - [Keyboard][V1.2] The keyboard name of notification bar is incorrect
     -- since keyboard show timing is depends on 'mozbrowserresize' event,
        so call 'showIMESwitcher' in the end of 'resizeKeyboard'
        to make sure refresh latest information at each time while keyboard layout is chnaged.
     -- ignore mozbrowserresize event while keyboard Frame is hidding.
