This issue has been Available for over a year. If it's no longer important or seems unlikely to be fixed, please consider closing it out. If it is important, please re-triage the issue.

Sorry for the inconvenience if the bug really should have been left as Available.

cc'ing more people in WebGL and ANGLE to see what is appropriate next step here.

Thanks.

Until:

- the typ harness is updated to use the new planned TestExpectations format
- Telemetry is changed to use it too
- the GPU tests are rewritten to use this TestExpectations format

then we won't have information about whether these tests which are marked flaky are actually still flaky.

It would be risky to re-enable them until that point.

Archiving this old issue for the time being.
