> Yeah, I don't think this is the right place to set the scrollView's background color. I think we should just store the color coming in from the layer commit, then decide where to apply it in response to gestures elsewhere.

Just so you know, we do already cache the color. We cache it in WebPageProxy::didCommitLayerTree.

New patch forthcoming!
