James, could you, please, take a look?

This is happening on Tier 1.

Patch at https://phabricator.services.mozilla.com/D49832

Patch works on early beta and late beta: https://tinyurl.com/y2epdyxu Can we land it on integration?

Nevermind that, webaudio failures are still present on today's beta sim: https://treeherder.mozilla.org/#/jobs?repo=try&group_state=expanded&resultStatus=pending%2Crunning%2Ctestfailed%2Cbusted%2Cexception&classifiedState=unclassified&author=rgurzau%40mozilla.com&fromchange=ad4e908d3dac91b25d45830c7e382155e9bd8a14&searchStr=linux%2Cx64%2Casan%2Cweb%2Cplatform%2Ctests%2Ctest-linux64-asan%2Fopt-web-platform-tests-e10s-18%2Cw%28wpt18%29&selectedJob=273150527

https://treeherder.mozilla.org/logviewer.html#/jobs?job_id=273150527&repo=try&lineNumber=11092

yesterday's beta-sims were build on https://hg.mozilla.org/mozilla-central/rev/ad7a152bc66c0d411a6fb0b210d675abed9693c7 that didn't contain the changes from the latest wpt-sync here https://hg.mozilla.org/mozilla-central/pushloghtml?changeset=51a716d8967713687defb9173047adeab92d2e29

that means there are new webaudio failures on beta-sims that look like: https://treeherder.mozilla.org/#/jobs?repo=try&group_state=expanded&resultStatus=testfailed%2Cbusted%2Cexception&author=rgurzau%40mozilla.com&fromchange=ad4e908d3dac91b25d45830c7e382155e9bd8a14&searchStr=wpt&selectedJob=273153434

https://treeherder.mozilla.org/logviewer.html#/jobs?job_id=273154116&repo=try&lineNumber=7721

Filed Bug 1591810 to track the new failures. I guess the patch in this bug is good to go.

Got into central here: https://hg.mozilla.org/mozilla-central/rev/2a0388b73b8c28971ed5de1b5f601e4bd0e6c216

The changes for testing/web-platform/meta/fetch/metadata/appcache.tentative.https.sub.html.ini were left out on that push and are failing on beta as release simulation.

nvm the last comment, it fails on beta as release because it wasn't uplifted to beta yet, the changes are present on integration.
