spring-configuration-metadata : when two properties have the same Object type F3 fails on the later ones

[space88man]

Describe the bug
When @ConfigurationProperties has more than one field of the same non-primitive type, F3 navigation fails on the later(lexicographic) ones.

To Reproduce
Editor -> application.yml -> press F3 on property

Observe:

• app3, app3.service1.** - navigates with F3
• app3.service2 - does not navigate
• rename service2 to service0: now app3.service0 navigates but app3.service1 stops working

Sample
gh-sts4-sampleV2.zip
We add a primitive type field to app3, OTW it won't navigate see #1030

app3:
  value: true
  service1:
    host: 1.2.3.4
    port: 5000
  service2:
    host: 1.2.3.4
    port: 5000

@ConfigurationProperties(prefix = "app3")
public class Settings3 {
    public static class Endpoint {
        private String host;
        private int port;
        public String getHost() {
            return host;
        }
        public void setHost(String host) {
            this.host = host;
        }
        public int getPort() {
            return port;
        }
        public void setPort(int port) {
            this.port = port;
        }
        
    }

    private Endpoint service1;
    private Endpoint service2;
    private boolean value;

    public Endpoint getService1() {
        return service1;
    }
    public void setService1(Endpoint service1) {
        this.service1 = service1;
    }
    public Endpoint getService2() {
        return service2;
    }
    public void setService2(Endpoint service2) {
        this.service2 = service2;
    }
    public boolean isValue() {
        return value;
    }
    public void setValue(boolean value) {
        this.value = value;
    }
}
