If the enclosing class is non-generic, the old behavior is preserved to create a single link to the inner class. The reason for this is that a dedicated link to the enclosing class itself provides little benefit, since it can be easily reached via the "Enclosing class" link of the inner class. Also, linking the enclosing type in absence of type arguments makes it hard to see that there are two links and easy to click on the wrong link by mistake.
