Signal follower can change its own parameters - Should it?

I’m not sure if i should interpret this as a bug, but when trying to influence a signal follower its own parameters, the level meter only shows left output and the parameters are not touched.
The signal follower is allowed to change its own parameters though (not that i am interested in this myself, but i just noticed when fooling around with it).

Perhaps it should also belong into the N/A chain?
