Unfortunately https://results.webkit.org/?suite=api-tests&test=TestWebKitAPI.EventAttribution.Basic doesn't have lot of data for iOS release because of Bug 229994.

Tried on both iOS 14 simulator and BigSur, but I was not able to reproduce the timeout locally using run-api-tests --iterations 50 --ios-simulator TestWebKitAPI.EventAttribution.Basic --release.

Try just `TestWebKitAPI.EventAttribution`, bet we have some test results poisoning one another.

I'm looking into this. I bet adding more tests caused state to be left on disk from one test affecting a future test.
