Comment 4 for bug 1558447

That sounds about right. Confusingly the email refers to the latter patch saying it might be fixed by that. Unfortunately it looks like the revert has been part of the fix and we already had both in vivid when undoing the revert was not only no longer needed but probably even fatal without the misapply.

While looking through the current history of that file, I noticed yet another tweak around that area. So maybe, while reverting the wrong revert of the revert, it might be worth looking at
