test: add unexpected behavior repro test

I'm opening this PR as a draft since I have not had the time to fix the issue yet. This test highlights what I believe to be an issue related to file watcher owners.

Basically, given a specific series of updates to files under watch, the link between the test file and its dependency is being lost.

Thanks for bringing this up, I realised this bug as well, and I forgot to create an issue for it 😄

I'm closing this since another PR it's proposing a fix 🚀
