hasChildrenClass not adding class on render function

[samroberts707]

Describe the bug

I'm using the craft.navigation.render function to load my nav. I've declared the hasChildrenClass as per the docs but the parent LI doesn't have the defined class.

Here is what my render function looks like:

{{ craft.navigation.render('mainNav', {
     ulClass: 'nav-items',
     liClass: 'nav-item',
     aClass: 'nav-link',
     activeClass: 'nav-active',
     hasChildrenClass: 'nav-has-children',
}) }}

Here is a screenshot of what is rendered from browser inspection. (I've manually removed the HREF value)

Steps to reproduce

1. Create Navigation with Children
2. Render navigation in template using the .render function

Craft CMS version
