/service-workers/service-worker/svg-target-reftest.https.html times out

@upsuper why does this test time out? Running it locally it seems the reftest-wait class is removed.

[upsuper]

It seems if it times out, there is probably some issue around either the service worker registration or page loading? Maybe somehow the given scope has other service workers registered which leads to some conflicts?

I have no idea... Maybe @wanderview has some idea since he wrote this test.

How are you running this test? Firefox passes the test in mozilla's infrastructure and when run from our ./mach web-platform-tests CLI tool.

I probably will need @jgraham's help here since I don't know how our mozilla setup differs from other configs.

The test passes for me locally using wpt run firefox service-workers/service-worker/svg-target-reftest.https.html, with either --reftest-internal or --reftest-external.

This test was timing out across four browsers when we ran it against revision 6736e3f46b of WPT back in mid-April. In the latest test collection, this test only timed out in Safari:

It may be an intermittent timeout, or maybe some change to the implementations or the results collector corrected the problem.

OK. @cdumez do you want to take a look for Safari? Locally for me it removes the reftest-wait class in Safari 11.1 and TP.
