Manish - Can we skip this on stylo?

I did a lot of retriggers:
https://treeherder.mozilla.org/#/jobs?repo=autoland&filter-searchStr=rs7&fromchange=f5644dde03c96747c4861124024ab39f22f8c274&tochange=765fb89f4f893ec0cd7e8666d89bb9b578e212ca&selectedJob=82544209

and the root cause is bug 1344619.

:hiro, as the patch author for bug 1344619, can you take a look at this?

Comment 5

[Joel Maher ( :jmaher ) (UTC -8)]

note: possibly this should live in the Core::DOM:Animation component as that is where the patch that broke this came from.

Comment 6

[Hiroyuki Ikezoe (:hiro)]

I am hoping bug 1341985 (which has been landed into mozilla-central now) fixes this failure.
Would you mind waiting a couple of days?  If the failure still persists, I will disable it. Thanks.

thanks for the update :hiro, that sounds like a good plan.

Thank you bot for the reminder. There are four failures on try after landing bug 1341985, but all of them does not include the fix for 1341985.  I am now convinced that bug 1341985 fixed this failure. 
Thank you Joel and Geoff for your patient.
