It looks like a PMediaParent actor is being destroyed on a background thread (it is marked as threadsafe refcounted, it appears, despite being managed by PContent which is firmly main-thread only).
Every managed actor contains a RefPtr to the manager actor within IPC code (https://searchfox.org/mozilla-central/rev/4ce36232b265b53de4fb7eb754430f94e262bbbe/ipc/glue/ProtocolUtils.h#335), so this actor is actually not safe to be destroyed on a background thread, so probably shouldn't be threadsafe refcounted.
