Color schemes selection is not undone despite clicking on undo changes

On color schemes tab, click on something like "white on black". Observe that the background changes to black. Then without closing the window, click on "undo changes and close".. nothing happens, it stays black.

It should make it white again if it is undoing the change.

I think that the fixes in the way color scheme preferences work has fixed this.
