Icon does not show if <nolink> used as menu link

MR opened for proposed change.

@MrDaleSmith
I have installed Simple Menu Icons with Version: 3.0.x-dev as mentioned.Tried to add icons in menu, After click on save the menu is not saved. I checked in logs I saw one error related to same module.The error is (Undefined constant "FILE_STATUS_PERMANENT" in simple_menu_icons_menu_link_content_form_submit()).
So I am creating new issue with link of this ticket

I believe that's unrelated to this issue and has been raised previously in https://www.drupal.org/project/simple_menu_icons/issues/3328904 🐛 Error: Undefined constant "FILE_STATUS_PERMANENT" in simple_menu_icons_menu_link_content_form_submit() Fixed

@MrDaleSmith Then we should hold this issue till the error issue will close, because when the error will fix then only we can save menu with icons and no link behaviour.

That'd be a call for the maintainers, but seems like overkill to me :)
