    [NTUSER] IntWinListOwnedPopups: Exclude default IME window from the list (#5069)
    
    And in IntShowOwnedPopups: Remove the window owner check hack as it's no longer
needed.
    Based on my observation, the owner of the default IME window can change and it depends
on
    the window that is being focused.
