I dont have windows and cant check the failing test. Is it a race condition or an actual issue? Can we rerun the test?

I ran the tests on Windows 10 with Node v.20.18.1, everything seems to have passed, but only with node test.mjs (the same command as the one used by the CI). npm test didn't work for me, failing multiple cases.

windows still has some flakiness in tests thanks to some double events. i dont remember exactly what off the top of my head but a re-run made this pass for now
