What information was incorrect, unhelpful, or incomplete?

If the URL is relative, it is relative to the HTML document's base URL.

Is it really the HTML document's base URL that is being used here? I didn't manage to drill down to the bottom of the https://spec.whatwg.org/ specs, but from some experiments it looks like what is being used here as base URL by recent Chrome and Firefox at least, is the URL of the script with which the given worker was constructed.

I believe you are right: it should be relative to the worker's URL.
