This only happens in non-accelerated mode. Looks like `DrawingAreaCoordinatedGraphics` still redraws everything in non-accelerated mode when the layer tree state is frozen.

This is a regression from https://github.com/WebKit/webkit/commit/94d2fcd0c2eb2399b31253290153676de5cf21ee, as that change relies on freezing to prevent page redraws.
