oldUnobscuredContentRect.y() < 1 is true for RTL pages. Please test one.

I think this is no longer true. In RemoteLayerTreeDrawingAreaProxy::commitLayerTree(), didCommitLayerTree() is before requestScroll().

Can you double check that the zoom rect used here does not depend on the ContentInset of UIScrollView?

Here we are only using the bounds.
