Bug 240821 – REGRESSION (248593@main): [ Monterey wk2 ] webgl/max-active-contexts-webglcontextlost-prevent-default.html is a flaky timeout/failure

• Status: NEW
• Component: WebGL

[Karl Rackler]

Description:
webgl/max-active-contexts-webglcontextlost-prevent-default.html

The first failure I saw on the dashboard was on 3/18/2022 at r291477, but this does not appear relevant to causing this issue.  This test has been flaky for its entire history on the dashboard.  This is affecting Monterey Release wk2 X86_64.

This test was completing in ~2 seconds until https://commits.webkit.org/248593@main landed

This test went through a period of passing consistently on Monterey until 248593@main landed.  The test then began to consistently timeout on Monterey wk2 Release and Debug on x86_64.  

The test continued in the same state until approximately 5/23/2022 at 250896@main. The test continued to flaky time out on Monterey wk2 Debug on x86_64 and flaky failure on Monterey wk2 Release on x86_64, which has continued until this day.  

Updating test expectations while the issue is investigated.
