imported/w3c/web-platform-tests/workers/interfaces/DedicatedWorkerGlobalScope/postMessage/structured-clone-message.html

is a flaky crash on EWS iOS wk 2 only. 

Affected EWS Queue:
https://ews-build.webkit.org/#/builders/51

First occurrence appears to be here:
https://ews-build.webkit.org/#/builders/51/builds/12203

Most recent occurrence was here:
https://ews-build.webkit.org/#/builders/51/builds/12322


There is no crashlog produced with any of these reported crashes on EWS, the results just simply indicate that the test crashes. Also, because this test only crashes on EWS, and not on any other platforms, I cannot reproduce the crash anywhere.
