None of these stack frames are in Chromium code at all. Any clues as to what's going on, CF peeps?

With MSan we don't track where threads were created like we do with ASan, so I think this is all we're going to get here. It looks flaky and CF has it marked as unreproducible. I'll leave it open for now in case you want to try to triage it, but WontFix seems reasonable in this case.
