restartOnFileChange option is broken (again)

[scottohara]

(See similar issue from 2015: #1640)

Expected behaviour

✅ When restartOnFileChange: false, after a test run completes, saving a test file re-runs the test(s)
✅ When restartOnFileChange: true, after a test run completes, saving a test file re-runs the test(s)

Here I saved test.js three times, and it ran four times (initial run, plus 3 x saves):

Actual behaviour

✅ When restartOnFileChange: false, after a test run completes, saving a test file re-runs the test(s)
🚫 When restartOnFileChange: true, after a test run completes, saving a test file does not re-run the test(s)

Here I saved test.js four times, and it ran once (initial run only):

Steps to reproduce

I have created a trivial reproduction of the issue here:

Thanks for the report. I can reproduce it, but not every time. It looks like it is caused by the race condition between the stop and execute signals sent to the browser. I'll look into it more.
