Okay, so the test loads PAGE_URL on a discarded browser. This causes a process switch from about:blank -> example.com. It expects a location change for PAGE_URL_BEFORE, but depending on when the process switch happens we may or may not drop that event because of comment #21.

Interestingly this doesn't really fail if run once, but with `--repeat n` it will consistently fail in the 2nd or 3rd run. Probably because we now have a preallocated example.com process.
