how to express nested objects as scaladoc entity links?

hi,

given code like this:

package foo

object bar {
object foobar
}

trait baz {
/** Returns [[foo.bar.foobar]].
*
* @see [[foo.bar.foobar]]
*/
def foobar = foo.bar.foobar
}

and I want, as you can see, an entity link to a nested object, but the output,
i.e. scaladoc in a browser, shows no link but just plain "foo.bar.foobar"

how can I express this that the doc will show an actual link?
