My internet's too slow. Can someone copy-paste the log into the reftest analyzer and capture a screenshot?
Seems like the border isn't rendered, probably an incremental layout bug.

:( I was afraid of this. See https://github.com/servo/servo/pull/10246#issue-144074395 for details. We should probably disable this until #10245 is implemented, and see if that can make it more reliable.
Filed #11069 to disable.
Huh, this doesn't look like it's disabled...
Can't we just spinloop for 200ms or something? Edit: nevermind you addressed that in the other ticket.
Wait, we support transitionend now right? So we can just wait for that event in the test.
Yes.
@jdm According to http://testthewebforward.org/docs/reftests.html, we can't actually wait for anything in a reftest in Servo, given we don't support mutation observers, no? :(
We have the reftest-wait classname in the HTML element, isn't that enough?
No @emilio, we don't support mutation observers.
technical note: the implementation in wptrunner uses mutation observers so the screenshot will be triggered in the microtask checkpoint after the class is removed
We support reftest-wait in rust code
PR to disable: #14288.
This test is still disabled.
Oops.
This is no longer disabled in layout 2020, so I'm going to close this one.
Seems intermittent again: https://github.com/servo/servo/actions/runs/11061095878/job/30733506496

We haven't seen this for months, so I think we are safe to close this again.
