imported/w3c/web-platform-tests/IndexedDB/keypath-special-identifiers.htm

This test has been flaky failing for all visible history across all platforms 

I was not able to reproduce the failure with iteration testing

This is actually pretty surprising. This means that it's not contention for resources with other tests, but enormous stalls or deadlocks even in single process operation.

Expectations updated at https://bugs.webkit.org/show_bug.cgi?id=228241 as the test is no longer flaky.
