This is a rework of #25323.
Consider two platform views, each have layer A, and B. Layer A can overlap B, but because the current code doesn't join their rects, the result is that layer A doesn't know it will overlap B. As a result, layer A ends up missing some content.
This change always joins the rects of the layers underneath the current platform view.
