Add Linking to constructors in WebIDL

[mwatson2]

[Constructor]
interface Foo
{
...
};

If I document the Foo constructor with <dfn>Foo</dfn>, then all links to Foo in the document point to the definition of the constructor (#dom-foo) and not to the IDL (#idl-def-foo'). No amount of additional attributes on thedfn` element seems to fix this.

@mwatson2, sorry, can you provide just a tiny bit more text so I can make sure we fix this properly? Like, what would you like to describe about the Foo constructor. Some sample text/markup would be really helpful to see how to wire everything up.

Ok, looked into this a bit more... Yeah, we sadly don't support this yet.

changed to feature request.
