Ryan, I see you are the owner of bug 1366050. Is this something we can accept? Or should we look for an improvement?
Also, if I've blocked the wrong bug from the patch, please let me know.

This is a result of including Stylo code for this platform.  We've seen the same increase on other platforms (see bug 1378667 and others).

So, it seems reasonable to accept.
