Trying to profile WebRender in a local Windows build gives me a profile like this: https://perfht.ml/2S6ZkIv

All of the rust WebRender stack frames are showing up as the same, unrelated symbol.

Ted, the dump_syms file doesn't seem to contain any rust functions. For example, I'd expect the string cascade_style to show up somewhere but it's not there. Have you seen something like this before?
