WebKit has a "ASCII whitespace without FF" definition that is used for JSON/HTTP/XML. Perhaps we should add the same definition to Infra?

See also https://fetch.spec.whatwg.org/#http.

And yeah, it's not clear to me that 1.1 is actually supported. Chromium and WebKit seem rather lenient and allow data:text/xml,<?xml version="1.2"?><test/> which I don't think is permitted by the XML specifications, and Gecko rejects that and also rejects 1.1.
