this has 33+ instances in the last day, I would like to get a fix in for this soon:
https://brasstacks.mozilla.com/orangefactor/?display=Bug&bugid=1346925&startday=2017-03-06&endday=2017-03-14&tree=all

this might be the range for where the regression was introduced:
https://treeherder.mozilla.org/#/jobs?repo=autoland&filter-searchStr=stylo%20reftest%208%20opt&tochange=b2eb2db87c0f2bd57db93138cb2238bc5995ff9e&fromchange=c33bd947c1c9aac387d55cddd23be8ab7a512ffd

rs8 is the key chunk, but there are many other failures as well.

I wanted to ni these users: [e-mail], [e-mail], but they commit to mozilla-central and do not have a bugzilla matching email :(

bholley, can you take a look at this?  I see your email associated with many of the pushes in the suspected range.

Comment 3

[Bobby Holley (:bholley)]

Looks related to bug 1303229. Emilio, can you take a quick look? We should disable the test on stylo if we can't fix it quickly.

Comment 4

[Emilio Cobos Álvarez (:emilio)]

I believe this will go away once bug 1328652 lands.

I haven't seen any other issues in a while, this might be resolved, will wait another day or two :)
