Navbar role breaks validator

Yii 2.0 General Discussions
1

What is the use in yii2-bootstrap/NavBar.php of:

line




102 if (empty($this->options['role'])) {

103     $this->options['role'] = 'navigation';

104 }

https://validator.w3.org gives a warning on an useless role in a nav tag.

So, should we remove it?
