Comment 27

[Chris Peterson [:cpeterson]]

When trying to enable WPT for Fission with TSan in bug 1696042, this rare intermittent test failure reproduced 3 out of 3 retriggers:

https://treeherder.mozilla.org/jobs?repo=try&revision=e2487391f036693313bd60adfb1ce49516ba959f&searchStr=tsan

If someone cares about this before-prepare-iframe-parse-error-external-module.html test, enabling Fission with TSan may be a way to reproduce this test failure more reliably.
