    gtkwidget: Do not check event sequence state before cancelling gesture
    
    The sequence should be cancelled from the gesture despite its current state.
    Also, there was a piece of pointer emulation that was not dropped here,
    maybe breaking things further for the pointer emulated touchpoint.
