### Issue description

The "Lookup Symbol" button don't appears for custorm class names.
Related issues: #68475,  #73167.
I tried apply #68311, #69473 and #73196. It don't helps.
The `Ctrl+LMB` works right for all cases.

### Steps to reproduce

Right click to the `CustomClassA` symbol in the `custom_class_b.gd` anywhere. The `Lookup Symbol` button don't appears in the context menu.

### Minimal reproduction project

Example from  #68475.

				continue;
			}
			if (i > 0) {
				r_arghint += "\n";
			}
			r_arghint += _make_arguments_hint(E, p_argidx);
			i++;
		}
		return;
	} else if (call->is_super || callee_type == GDScriptParser::Node::IDENTIFIER) {
