Bug 206834 – [ Macos iOS ] http/tests/workers/service/basic-timeout.https.html is flaky failing

• Component: Tools / Tests
• Status: NEW

[Jacob Uphoff]

http/tests/workers/service/basic-timeout.https.html is flakey failing on macOS and iOS 

I was able to reproduce the failure by running the test in iterations x5000, it reproduced multiple times.

The test has been flaky for the whole visible history, so no regression point.

WPE and WinCairo ports are also flaky failures.
