This regression looks to be in query.html: https://treeherder.allizom.org/perf.html#/comparesubtest?originalProject=mozilla-inbound&originalRevision=d6059530b031&newProject=mozilla-inbound&newRevision=cfc1820361f5&originalSignature=5d92d35aeb763b5852f6e260466d6b9b8fc17a56&newSignature=5d92d35aeb763b5852f6e260466d6b9b8fc17a56 I don't see any other tests regressing with this change. As it stands Linux64 is the only platform we run dromaeo_dom on, so I am not sure if this would affect osx or windows. :shu, can you look into this regression to see why it is happening and what if anything we can do about it?

appears to be the same bug up front.

As a note, this sort of thing is why I was so opposed to completely shutting off dromaeo_dom.

Most likely a dup of bug 1212183 like Jan said. I'll push the fix today.
