Status: Fixed (was: Assigned)
I'm unable to reproduce this issue from the build/test case provided in the detailed report and the detailed report does mention "Reproducible: NO".

Note that this issue was reported on Sept. 22 and some data races were fixed on Sept 28 here:
https://chromium-review.googlesource.com/c/chromium/src/+/687817

Marking as fixed for now. Please reopen if this issue reappears. Thanks.
