```
 0:13.62 pid:1705 [1722] Assertion failure: mPromise, at /Users/cm/Work/gecko-dev/obj-aarch64-apple-darwin21.4.0/dist/include/mozilla/MozPromise.h:1513
...
Mozilla crash reason: MOZ_ASSERT(Promise)
....

I hit an assertion in MozPromise after getting a decoded output from `AppleVTDecoder`. However, I could not reproduce it anymore so I can only upload the stack shown on my terminal. It must be a race somewhere. The fuzzer might help us to catch it.
