:bradwerth, since you are the author of the regressor, bug 1737682, could you take a look?

I can probably fix this by making the test less stringent. I'll wait until the regressing Bug is closed as resolved, because I want to make sure my patched test will merge.

This appeared as a tier 1 failure here . It is intermittent for now.

Summary: Intermittent [TV] dom/media/test/test_video_low_power_telemetry.html | Test 1 enum 3 should have either 1 or 2 occurrences; found 0. → Intermittent dom/media/test/test_video_low_power_telemetry.html | Test 1 enum 3 should have either 1 or 2 occurrences; found 0.

The patch will hopefully resolve this intermittent failure. If it doesn't, it will give us more information on how/why the test is failing and inform how to fix it. I'll keep the bug open until we know which case is happening.

This is probably fixed. I'm going to push one more change to the test to reduce the time it takes each iteration.

I believe this is fixed.

I'm going to close this. I don't think it will reappear.
