1698689 - Fix and re-enable dom/url/tests/test_url.html for Fission TSan

Status: RESOLVED WORKSFORME

(Core :: DOM: Core & HTML, defect, P3)

Description

[Chris Peterson [:cpeterson]]

ahal tried to enable mochitest-plain for Fission on linux1804-64-tsan/opt in bug 1694833. Unfortunately, there are some new TSan test failures with Fission. mochitest-plain already runs on linux1804-64-tsan/opt for e10s (non-Fission), so Fission is presumably causing these new failures.

Try run:

13 possible regressions (and 17 known issues):

Resolving as WORKSFORME because I re-triggered the Fission TSan tests 5 times on try and didn't see any failures:
