Go to Implementation on interface method does not work for inherited implementations

Apache NetBeans 30

What happened

Go to Implementation (Ctrl+Alt+B, or context menu > Navigate > Go to Implementation) does not work on interface methods whose implementations are inherited from classes that themselves aren't declared to implement the interface (but subclasses are). The "Ⓘ" badges in the editor gutter are correspondingly missing.

This makes it more difficult to locate method implementations from a call site that invokes the method from the interface type, and it makes it misleadingly look like there are no implementations of the method.

How to reproduce

class Example
{
    interface A
    {
        CharSequence a();
    }
    
    interface B extends A
    {
        @Override
        String a();

        String b();

        String c();
    }
    
    static class AImpl implements A
    {
        @Override
        public String a() { return "a"; }

        public String b() { return "b"; }
    }
    
    static class BImpl extends AImpl implements B
    {
        public String c() { return "c"; }
    }
}

On B::a anb B::b, Go to Implementation (Ctrl+Alt+B, or context menu > Navigate > Go to Implementation) does not work, although these methods are implemented by AImpl (in the context of BImpl).

In addition, no "Ⓘ" badge is shown on B::b, although interface B is fully implemented by BImpl.

Did this work correctly in an earlier version?
