Parsing html with an invalid url will crash Parse
→ github.com/willnorris/microformats
The microformats parser will crash when url.Parse returns an error. The "parsed" will be nil and this will crash inside ResolveReference.
I found it while parsing: https://chat.indieweb.org/dev/2018-04-17. This will also crash when run with gomf https://chat.indieweb.org/dev/2018-04-17
