Testing mega menu implementation. menu_item_extras is using item.content render array for menu twig. It seems if we support rendering of item.content in menu--navbar template we can also support extra menu content that is coming from menu_item_extras module.
For this to work you also need to override template in custom theme, for example you define templates/navigation/menu--extras--main--navbar.html.twig and in it put:
{% extends "@bs_bootstrap/navigation/menu--navbar.html.twig" %}

Here is a patch. Seems it works fine but more testing is needed in real projects.
