Bug description

I have a class that implements an interface. I forgot to use the interface and used the concrete instead, but when I tried to find the usages of an implemented method, my editor went to the contract instead of the usage.

I am injecting my UserRepository somewhere, and there I am using the findByEmail-method. When I try to find the usages of my method, as long as I implement the interface, go to usage goes to the interface:

Schermopname.2026-08-30.om.09.25.24.mov

It also might worth noting that when I remove the contract, the references badge appears with 1 reference:

With the contract, no references count is shown:

(but it does show on top)

Steps to reproduce

1. Let a class implement an interface
2. Inject the concrete in another class.
3. Try to go to usages of the overridden method in the concrete class. It goes to the interface, not the concrete usage.
