Find someone to own this?
Neil, do we think we should fix this for 61?
This is very likely a crash revealed by 1439875 and friends. I'm assuming that the call to SetNonClientMargins either in or inside the call to HideWindowChrome is deleting this or mWindow or somesuch, since it looks like it sends events and invalidates.
Thanks, Neil. Hey emilio, assuming this is fallout from bug 1439875, do you have some cycles to investigate this?

hi, could you request uplift to 61 beta in case you deem fit to do so?
Yes, this should be uplifted, but also with the patch in bug 1463819. I'll request once both patches land.
