They seems to fail randomly. For e.g.: In https://ews-build.webkit-uat.org/#/builders/19/builds/1323 these tests failed in run-api-test and re-run-api-tests steps, however the patch has nothing to do with WTF.

Seems like this bot consistently reproduce this issue. 1533514 2 webkit-bug-importer 2019-05-06 13:16:06 -0700 <rdar://problem/50510046> 1534070 3 aakash_jain 2019-05-07 13:05:23 -0700 Haven't noticed this flakiness for a while. It's possible that there was some issue with ews153 making it very slow and causing test to time out.
