[task 2019-12-13T20:58:20.784Z] 20:58:20 INFO - GECKO(3412) | [GFX1 25]: MessageChannel failed to close. GetLastError: 6

6 is ERROR_INVALID_HANDLE, so that seems to be the same failure that was being investigated in bug 1120485 (which added the assertion that's failing here) and resolved incomplete.

[Jed Davis [:jld] ⟨⏰|UTC-7⟩ ⟦he/him⟧]

This is probably the same underlying issue as bug 1120485 and maybe also bug 1564899 comment #2.

I suspect the cause is a double-CloseHandle somewhere else, and HANDLE value reuse (which is a thing) causing it to sometimes close unrelated handles, which means we have essentially no way to find out where the problem is without STR.

[Jed Davis [:jld] ⟨⏰|UTC-7⟩ ⟦he/him⟧]

Also let's maybe not title this bug with a very general message that means “assertion failure in code written by graphics people”, nor use it as a crash signature.
