Since the canvas element of a -webkit-canvas is not attached, it won't highlight anything when hovered in the Resources tab. Instead, we should highlight all nodes that are using that canvas, similar to how they are listed in the Canvas details sidebar.

The communication between the frontend and backend is async. So maybe by the time the frontend says "Highlight Nodes [A, B, C]" the backend as removed Node B. We should still highlight A and C, but here we would bail.
