Mouse over a variation after the game has been scored doesn't display correctly

I couldn’t find exact match for this bug in forums so I created a new thread.
I came across my old game that I use in my KGS profile to lure people here.
I noticed that mouse over on a variation displays wrong when the game has been scored. The stones that are marked dead stay “ghosted out” in the variation displaying.
I tried this for a recent game also at and it was the same.

Bah indeed, thanks @Pempu!
