Bug 1361807 - Use the transformed bounds for WebRenderRefLayer, as it doesn't push a stacking context.
59 bytes, text/x-review-board-request
I made an error in bug 1360246, in the RefLayer implementation. The RefLayer doesn't push a stacking context, so we need to transform the bounds by the layer's transform before we can take it as relative to the enclosing stacking context. We do this for the WebRenderDisplayItemLayer and WebRenderTextLayer already, and used to do for WebRenderRefLayer, but I accidentally removed it and didn't notice. The reftests don't catch this either because they don't create iframes, I guess.
Actually even reftests with iframes wouldn't catch this, since it has to be a subwindow with a separate layer tree. I have a patch coming soon.
