storage/indexeddb/getdatabases.html

Is a flaky failure on Windows-EWS.

It's also showing up as a flaky failure on the open source: https://results.webkit.org/?suite=layout-tests&test=storage%2Findexeddb%2Fgetdatabases.html

There was a constant failure previously that got fixed at https://trac.webkit.org/changeset/280524/webkit. Not sure if this is a new failure or something that's related to the previous bug (https://bugs.webkit.org/show_bug.cgi?id=228692).

Seems that the test first failed at this time at r280719

Flakiness on EWS seems to have started at around this build https://ews-build.webkit.org/#/builders/10/builds/101989
