Bug 182366 – Layout Test http/tests/resourceLoadStatistics/non-prevalent-resource-with-user-interaction.html is flaky

• Component: New Bugs
• Status: RESOLVED FIXED

[Matt Lewis]

The following layout test is a flaky timeout on macOS WK2

http/tests/resourceLoadStatistics/non-prevalent-resource-with-user-interaction.html

Probable cause:

The timeouts go back further than the flakiness dashboard shows.

Skipping this test seems to have caused http/tests/resourceLoadStatistics/non-prevalent-resource-without-user-interaction.html to time out.

[Alexey Proskuryakov]

Perhaps running http/tests/resourceLoadStatistics tests with --repeat-each will help determine which test is the real culprit. Matt, would you be willing to try that out?

Failing iOS-sim tests are unrelated.
