Comment (by Peter.Danecek@…):

 Okay, I see now how it would work. A port cannot depend on a specific
 variant of a port. So once it is already installed, the present version is
 kept. However, if it is not activated, the version with the correct
 variant is requested. In some way this makes sense.

 But the above is behaviour is quite ugly, inconsistent and misleading. So
 is there a way to avoid it?
