TestWebKitAPI.PublicSuffix.IsPublicSuffix is failing on some, but not all bots. It started failing on the x86 iOS GPUP bot on 12/14/2021 @ r287056. It then started failing on the arm64 iOS GPUP bot on 12/16/2021 @ r287127, and then the rest of the non-GPUP iOS bots on 12/17/2021 @ 287217. One of the Catalina Release bots started failing the test on 12/19/2021 @ r287237.

The test started failing on almost all bots (except Big Sur arm64?) at r287443, which itself seems unrelated.
I just built debug locally and I was able to reproduce this on the first try.
Disabled the failing subtest in r287773 to let the bots have a chance of being green.
