Preserve scroll position when restoring focus (#8401)

This misbehavior is particularly egregious because of our current strategy for updating a container in Fiber, but regardless -- if we restore focus to an offscreen node (ex: because it was reordered among its siblings) then we should not scroll the page to reveal it.

We could check the `overflow` computed style values before saving the scroll positions but that's unlikely to be any faster.
