Comment on attachment 676409 [details] [diff] [review] backout patch yes to this backout, pre-approving for aurora/beta even though this is only on inbound right now so that there's time to get this landed as early as it can be (ie: before tomorrow at noon PT) and we get this backout in our 17 Beta 4 builds.
