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.

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.
if (inherited_script->has_method(name)) {
				found_base_class = "script:" + inherited_script->get_path();
				break;
			}
			base_class = inherited_script->get_instance_base_type();
			inherited_script = inherited_script->get_base_script();
		}
		if (found_base_class.is_empty()) {
			while (base_class) {
				List<MethodInfo> methods;
				ClassDB::get_method_list(base_class, &methods, true);
				for (int j = 0; j < methods.size(); j++) {
					if (methods[j].name == name) {
						found_base_class = "builtin:" + base_class;
						break;
					}
				}
				ClassDB::ClassInfo *base_class_ptr = ClassDB::classes.getptr(base_class)->inherits_ptr;
				if (base_class_ptr == nullptr) {
					break;
				}
				base_class = base_class_ptr->name;
			}
		}
		if (!found_base_class.is_empty()) {
			int line = functions[i].get_slice(":", 1).to_int() - 1;
			Dictionary line_meta = text_edit->get_line_gutter_metadata(line, connection_gutter);
			if (line_meta.is_empty()) {
				
				line_meta["type"] = "inherits";
