    Revert "Bug 676077: Fix handling of Keyboard Input on Windows"
    
    The actual code that does the IM context code handling on Windows now uses the
    native Windows APIs to handle keystrokes, so this patch is no longer needed, as
    it was found that it instead caused issues.
    
    Pointed out in issue !2865.
    
    This reverts commit fd6ce9975e4cc9c090d07e7a6b0013d02b49ce26.
