Devin thinks we need to just not reset recording data in ~InspectorCanvas, as there is no reason to do that. I am skeptical that InspectorCanvas is not being destructed underneath ~CanvasRenderingContext, as that was the intent of the design.

Comment on attachment 329503 [details] Patch This looks good to me. The original patch however is triggering ASSERTions on the Debug bots, so I think it is about to be rolled out. In which case this can be re-included in that when relanding.
