I've noticed this error in Safari (9.1.2) and found in domain-task the following:

    if (!init.headers['Connection']) {
        init.headers['Connection'] = 'keep-alive';
    }

I see Connection listed here as a forbidden header name in the fetch spec.

Can this be wrapped in a !isBrowser condition?
