What would it look like if we just made the CustomElementMicrotaskQueue
refcounted? There's only two places this is used, right? One is in the
JavaScript context for the "root" queue. And another in an import. Or am I
missing something?

Right. Done.

 public:
-    virtual ~AudioDestinationConsumer();
-
-    virtual void setFormat(size_t numberOfChannels, float sampleRate) = 0;
-    virtual void consumeAudio(AudioBus*, size_t numberOfFrames) = 0;
+    static PassRefPtr<RefCountedCustomElementMicrotaskQueue> create() { return adoptRef(new RefCountedCustomElementMicrotaskQueue()); }
 };
