Luke, could you take a look at this?

[Luke Warlow]

I'm also unable to reproduce this using the iOS 18.4 simulator and minibrowser. This test isn't expected to actually pass because only Gecko seems to actually expose Workers inside of SharedWorkers, but I would expect a consistent set of errors as is marked in the expected file.

Given we don't expect this to actually pass I'd be inclined to Skip it if it's a flaky timeout. Running it doesn't really provide much?

[Anne van Kesteren]

I see, reportedly there is a problem with fetch_tests_from_worker at the harness-level so Skip seems acceptable.
