:automatedtester, I know :jgraham is out for a few weeks, could you help find someone familiar with the web-platform-tests harness to see if the harness is responsible for this bug and bug 1403428, or if we could surface the real error?

I have been able to reproduce this with --repeat-until-unexpected

The issue, on the face of it, appears to be a race condition.

The test that is failing to find the window is moving so looking more like a race condition.

Looks like we are not waiting for the browser to be fully registered. This looks like it is depending on bug 1363368
