    treeviewcolumn: Don't swallow motion/crossing events
    
    If the column is not clickable, it may make some sense to stop
    event propagation here for button events. However motion events
    should be left alone.
    
    Fixes treeview column resize pointer cursors, since that's
    implemented up the bubbling phase in the treeview.
