### Expected Behavior
AudioWorklets can be created and destroyed multiple times while `nodeIntegrationInWorker` is enabled.

### Actual Behavior
AudioWorklet can only be created and destroyed once. Upon creating a second AudioWorklet, the UI hangs indefinitely.

### To Reproduce
Electron Fiddle: https://gist.github.com/samuelmaddock/5430479c0a08eca3f693df2518c9887d

1. Load Audio Worklet examples directory: https://googlechromelabs.github.io/web-audio-samples/audio-worklet/
2. Open a demo and click start.
3. Navigate back and return to the demos directory.
4. Open another demo and click start.

UI should no longer be responsive.
