menu item for current page is missing a href tag for anonymous user

Question

drupal 8: Theme used "bartik".

If user is logged in, the active menu item has an <a> - tag, if not the tag is missing.

Is this the expected drupal behavior? btw. the same happens on the language switcher block.

How can i output the a-href tag for anonymous users? This would make theming menus much easier. Thx for any help or pointing me into the right direction

markup for anonymous user

    <ul class="clearfix menu">
.....
<li class="menu-item menu-item--active-trail">
    c
</li>

markup for admin user

<ul class="clearfix menu">
......
<li class="menu-item menu-item--active-trail">
    <a href="/drupal-8.0.3-clean/node/3" data-drupal-link-system-path="node/3" class="is-active">c</a>
</li>

I fixed this issue by overriding menu.html.twig. You could override menu--main.html.twig instead, if you just want to target the main menu:

menu.html.twig

<li{{ item.attributes.addClass(classes) }}>
  ##REPLACE THIS LINE:## {{ link(item.title, item.url) }}
  ##WITH THIS LINE:## <a data-drupal-link-system-path="{{ item.url }}" title="{{ item.title }}" href="{{ item.url }}">{{ item.title }}</a>
  {% if item.below %}
    {{ menus.menu_links(item.below, attributes, menu_level + 1) }}
  {% endif %}
</li>
