TestWebKitAPI.ProcessSwap.NavigateToDataURLThenBack seems flaky. In https://ews-build.webkit-uat.org/#/builders/20/builds/889, the test passed in run-api-tests step. However, in the immediately next retry step (re-run-api-tests), it failed.

Can we prioritize this? I am working on EWS for API tests, and this flaky failure is creating problem.
