Invalidate parent when scrolling child view back onto screen

This bug caused views which used to be quick-rejected to continue to not
be drawn because the parent's DisplayList no longer contained them. The
fix is to notice when offsetting a view puts it back on screen and invalidates
the parent appropriately.

Issue #21413554  offsetTopAndBottom requires invalidating parent when view becomes visible again
