I would expect that we need to convert from the coordinates of the
Scrollbar to the coordinates of the ScrollView's content area.
That is what FrameView::invalidateScrollbarRect does, and it is what
the old code did. So, this change seems wrong.

Same deal here. I'm surprised to see this differ from FrameView's
invalidateRect implementation, but maybe there is something more
subtle at play?
