Closing PR #43419 and removing active labels. 2108792 3 annevk 2025-04-03 23:03:25 -0700 Luke, could you take a look at this? 2110160 4 lwarlow 2025-04-10 04:54:46 -0700 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? 2110382 5 annevk 2025-04-11 01:13:55 -0700 I see, reportedly there is a problem with fetch_tests_from_worker at the harness-level so Skip seems acceptable. 2113857 6 lwarlow 2025-04-29 05:11:59 -0700 *** This bug has been marked as a duplicate of bug 291345 ***
