See https://github.com/whatwg/streams/pull/1333. Per https://github.com/WebKit/WebKit/blob/3d86280341992fc49475f4a9b7aca7f9c1edad01/Source/WebCore/Modules/streams/WritableStreamInternals.js#L717, WebKit has the same bug as the reference implementation did: it catches the exception caused by trying to call `undefined` as a function, and then attempts to error the stream with it. I don't believe this is observable since the stream is already erroring so the "TypeError: cannot call undefined" will not actually be exposed to the web developer. However, it's probably best to fix this.
