 1) workspace-namespace Tasks sync CustomExecution task should flush all data on close:
     Error: Timeout of 60000ms exceeded. For async tests and hooks, ensure "done()" is called; if returning a Promise, ensure it resolves.
      at listOnTimeout (internal/timers.js:531:17)

FYI @Tyriar looks like it's happening again.

@bpasero was this flaky or failing all the time?

[bpasero]

@Tyriar I think I have seen this at least twice in the past days. I am not sure it fails all the time. Note that our web integration tests only run as part of our product builds, so the frequency is a lot less.

@alexr00 I've disabled these tests on web, I believe this flakiness is the same as in the terminal where some terminals just don't launch #96057

@Tyriar Is this still an issue?
