    inspector: Properly update flashing hilight
    
    Previously, the inspector would not change the hilight while the
    previous hilight was still flashing.
    This is inconvenient while arrowing through the object selection
    treeview though where you want the currently selected row to hilight
    when arrowing quickly.
