The [`MOZ_ASSERT(mDecoder)`](https://searchfox.org/mozilla-central/rev/71aada9d4055e420f91f3d0fa107f0328763e40b/dom/media/webcodecs/DecoderAgent.cpp#244) crash was found in https://treeherder.mozilla.org/logviewer?job_id=470390514&repo=try&lineNumber=1391 on the Windows platform. I suspect this happens on all kinds of platforms. Below is the crash stack.
