Does not occur in Chrome or Safari 13. When using a Web Audio graph of the form: (BufferSource) -> (MediaStreamDestination) -> (HTMLMediaElement) disconnecting the BufferSource from the graph causes a malfunction, and garbage audio to be fed to the HTMLMediaElement. Setting HTMLMediaElement.srcObject = null works around the issue.
