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.

### Minimal reproduction project

Example from  #68475.

				bool valid;
				Variant::evaluate(op->variant_op, v1, v2, res, valid);
				if (!valid) {
					found = false;
					break;

				r_type = _type_from_variant(res);
				if (!v1_use_value || !v2_use_value) {
					r_type.value = Variant();
					r_type.type.is_constant = false;
				}
				found = true;
			} break;
			default:
				break;

	if (found && r_type.type.kind == GDScriptParser::DataType::BUILTIN && r_type.type.builtin_type == Variant::NIL) {
		found = false;
	}
	
	
	if (!found && p_expression->get_datatype().is_hard_type()) {
		r_type.type = p_expression->get_datatype();
		if (!r_type.assigned_expression) {
			r_type.assigned_expression = p_expression;
