inspector: Properly update flashing hilight
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.
