Hi Andreas,

The mailto URL scheme does not have any host component as per. its
different RFCs
 it is composed of:
-  a scheme component : mailto
- a path component containing a list of email addresses separated by commas
(as per your example)
- and a query component representing the email optional headers info

As such the WHATWG and the RFC3986 interpretation will all return null
because there's simply no host to describe.
