Re: [whatwg/url] Refusing a mix of numeric-only and BIDI domains (#543)

I agree that whatever revision is considered has to be rigorously tested.

I'm thinking combinations of representative chars from each bidi class plus
period, and verifying that for each, no char 'jumps over a dot' (reorders
to be in a different label). Is that something like what you did, Harald?
