It appeared on mozilla-beta and it looks like it's frequent ---> https://treeherder.mozilla.org/jobs?repo=mozilla-beta&group_state=expanded&resultStatus=success%2Cpending%2Crunning%2Ctestfailed%2Cbusted%2Cexception%2Cusercancel&searchStr=linux%2C18.04%2Cx64%2Cwebrender%2Cdebug%2Cweb%2Cplatform%2Ctests%2Cwith%2Csoftware%2Cwebrender%2Cenabled%2Cwithout%2Cfission%2Cenabled%2Ctest-linux1804-64-qr%2Fdebug-web-platform-tests-swr-nofis%2Cwpt14&revision=54b314ccce923051445805ff892d29e677d313ed&selectedTaskRun=VB1rzOxXTFmJTyWY05zTLQ.0

[Yulia Startsev [:yulia]]

This only impacts beta 111, the change is not present in nightly (for more info see https://searchfox.org/mozilla-central/source/testing/web-platform/meta/html/canvas/element/drawing-text-to-the-canvas/2d.text.draw.fontface.notinpage.html.ini#6) . Unfortunately, I missed that wpt-update automatically removed the [pass, fail] for this specific test, it was a lot of tests to go through.

You can see the mistaken removal here: https://phabricator.services.mozilla.com/D171235 -- just search for the file.

I've made a patch that fixes this, should this be uplifted to fix? I am not sure, as it may be too minor.

Comment 9

[Yulia Startsev [:yulia]]

This doesn't impact 112, it was fixed on nightly but not on beta and only affected 111: https://searchfox.org/mozilla-central/source/testing/web-platform/meta/html/canvas/element/drawing-text-to-the-canvas/2d.text.draw.fontface.notinpage.html.ini#6

The cause of the failure was an accidental line removed during the automated wpt-update.
