@romseygeek , the test was added in #138523. Is this potentially still under development and the tests just need to be disabled on release builds for now?

Encountered this on a PR and this prevents me from having a green pass with the test-release label on. Did not mute yet.

This is testing behaviour behind a feature flag so yes, it needs to be disabled for release builds. I'll open a fix.
