rules_webtesting test timeout on Bazel CI server

[achew22]

In the bazel-watcher project, I have been trying to make my integration tests more realistic. To this end I moved them to operate a real browser against the SUT. Unfortunately the test is timing out and I'm not sure what has gone wrong. Do you have anything you could point me to to help me debug this?

I haven't had much luck using the native browsers on ci.bazel.build; currently I only run Sauce-based browsers there.
