Julian, could you please take a quick look at this one when you get a chance? It's been failing ~30 times a week since it was added.

It looks like the previously downloaded screenshot from the iframe test gets reused here. We could try explicitly removing the downloaded file once the image has been loaded. However I couldn't reproduce it at all on try: https://treeherder.mozilla.org/#/jobs?repo=try&revision=8aa977cc8131a31a69955ccc3455d9b2a160cec1 I propose to try landing a fix and leave-open to see if it improves the situation.

I'll either fix or disable on windows. I think the issue is really related to windows reusing the file from the previous test. We generate the screenshot filename to look like: Screen Shot 2018-12-31 at 09.58.40.png ie "Screen Shot YYYY-MM-dd at HH.mm.ss.png". When the test fails, the shadow DOM test runs in the same "second" as the iframe test. I don't understand why deleting the file after the test doesn't fix the issue, but there might be caching involved somewhere else. I have two try pushes ongoing. One trying to move the file, if for any reason this works better than deleting the file. The other simply to wait one second between tests.

Waiting for one second seems to fix the intermittent: https://treeherder.mozilla.org/#/jobs?repo=try&revision=8ce5eb765be430f316afa12f5f744ef3369e288a Compare to the default: https://treeherder.mozilla.org/#/jobs?repo=try&revision=a632cf1f5f1edf1d6c456cf02e7a171fd084ad73 (moving the file showed no improvements compared to the default).
