[Iulian Moraru]

As the patch does in fact fix the frequency for the platforms that were listed in the bug summary, I'm changing this to "Intermittent".

Comment 14

[Daniel Holbert [:dholbert]]

Ran across this bug, since I hit this intermittent on a Try push.

The timeline here:

• This test was added in bug 1815252, originally named mq-non-matching-lazy-load.html
• It was intermittent, per bug bug 1817804; we landed a series of annotations and Emilio ended up recommending we annotate it as random (i.e. [PASS, FAIL]) everywhere, in bug 1817804 comment 19, so we landed that annotation.
• The test was then renamed upstream to add .tentative to the filename, and we sync'ed that rename in bug 1817808
• ... so our existing annotation no longer applies, and we've got this new intermittent bug filed for what is really the same test.

Emilio's recommendation in bug 1817804 comment 19 still stands, so let's just annotate this as [PASS,FAIL] everywhere like we did over there.

Comment 15

[Daniel Holbert [:dholbert]]

Attachment: Bug 1820695: Annotate WPT mq-non-matching-lazy-load.tentative.html as intermittent on all platforms. (No review, just restoring an inadvertently-lost test annotation)

The test was renamed, so we lost the old annotation, and the current
auto-generated annotation is insufficient. For more, see notes in:

Comment 17

[Daniel Holbert [:dholbert]]

^I just landed a patch to restore the annotation that we had added in bug 1817804, which should take care of this.

We'll want to uplift this patch to beta (v112), too. It has the earlier annotation from comment 7 which is insufficient to cover all platforms. My just-posted patch should apply cleanly there, I think.

Comment 18

[Daniel Holbert [:dholbert]]

Dianna, it looks like you're doing the 112 beta-uplifts -- would you mind bundling my patch from comment 16 into one of your next beta uplift pushes? It's a test-annotation-only change, to annotate a known-intermittent test that we got from upstream. Not-part-of-the-build, zero user-impact.

Or if anyone else with uplift-powers gets to it sooner, please go ahead. :) Thanks!
