Failure is unrelated to this patch.
I went with the approach of having IDLInterface<ReadableStream>, which works and has the benefit to keep the union conversion semantics the same.
This also automatically creates a Dom guarded object which is probably always wanted since processing ReadableStream can only be done asynchronously.

The alternative might be to introduce something like IDLReadableStream, but we might need to special case the binding generator for it and we would have to update the checks for the union conversion so that IDLReadableStream is part of the IDLInterface conversion.

Now that ReadableStream has a form, can FetchBody store it? The 'm_isReadableStream' has always been a bit confusing.

Should this not include ReadableStream?

Thanks for the review.

Yes, that is the plan.

Will fix it.
