This seemed to start with changes for bug 1379587, but note https://bugzilla.mozilla.org/show_bug.cgi?id=1379587#c44. Most failures are on debug, but perhaps 30% are opt. :florian - Disable on debug? Disable everywhere? Or can the test be made more reliable?

Locally this seems to help a lot (I can no longer make the test fail using --run-until-failure after applying this patch).

https://treeherder.mozilla.org/#/jobs?repo=try&revision=262d30b192466f0165ea5b7c6663dafd4711696f looks good.

Glad you found a solution - though I look forward to getting rid of these hacks once gandalf's stuff lands. :)

Pushed by florian@queze.net: https://hg.mozilla.org/integration/mozilla-inbound/rev/976a82102f13 make test_bug574663.html wait until the 'blank' attribute has actually been removed, r=mconley.

Is it something that we want to uplift in 57?

(In reply to Sylvestre Ledru [:sylvestre] from comment #12) > Is it something that we want to uplift in 57? Yes, but it's a test-only change to fix an intermittent, so (usually) doesn't need approval.

sure but still needs to be landed :)
