Multiple tabs displaying same image can forget dirty rect updates
We only use the dirty rect for a shared surface properly for the first WebRenderLayerManager requiring a resource update. Other instances using the same image may end up not updating at all. This will probably only be visible for really large, slow to download/decode images, but I could see it happening where you click a downscaled image and it opens a new tab to view the full sized image (but they point to the same resource).
