Add unmasquerade compatibility for new core navigation module

Added a patch.

Thank you! Great integration to add!
Let's get more opinions on a way to integrate, for example https://docs.gitlab.com/ee/administration/admin_area.html#user-impersona...

Curios if it needs cache metadata?!

Moreover we can display the block with quick links and so on.

Is there a way to configure how to display in navigation as I know nothing about it's API

I'm afraid I don't know much about the experimental Navigation module, but I am testing it out in a few projects to replace Gin Toolbar and Toolbar modules. I dumped all the $variables via hook_preprocess_navigation and hook_preprocess_navigation_menu and hook_preprocess_menu_region__footer but I see nothing about caching. Also missing is a 'weight' value or something, so adjusting the order is done by adjusting the order of the indexes in the ['items'] array itself.

So to answer your questions:

I don't think that is something you can set in the Navigation items

I'm not sure what you mean by this ?

Not that I know, you just add an item to ['items'] that is an array like this:

    $variables['items']['navigation.my_views_page'] = [
      'is_expanded' => FALSE,
      'is_collapsed' => FALSE,
      'in_active_trail' => FALSE,
      'title' => t('My view page'),
      'url' => Url::fromRoute('view.mycustomview.page_&'),
      'below' => [],
      'class' => 'navigation_content',
    ];

The class decides the icon. So easiest is to use existing classes and icons. But I have created items with a custom class and attached a library to add a CSS to set custom icon for the custom class.

I added the masquerade cache context to the main region footer menu

Can this be implemented with the new hook_navigation_content_top - see [#3487802]?

What I just tested manually is that you can move the provided menu link to the navigation user links menu, and then it shows up there. I think this issue predates that this section is a menu, might only be in 11.1 or even 11.2

You only have one of those links though, and we also have sites where we have non-editor users without toolbar/navigation access and then we like to put the link into a frontend menu.

Maybe the module could provide an extra link for that menu if navigation is enabled in hook_menu_links_discovered_alter? that's similar to how navigation defines its own dynamic links.

Just hit this on a project yesterday, and I think it belongs in the navigation itself, not the top bar. And the user menu is a logical place. So +1 to #1!

Also was super confused by #7 because I could not find this menu, until I reread the comment, and yes, the user block isn't a proper menu until 11.2 :)
