Description: 

The default HTML for the language switcher block contains an unordered list whose list items had an hreflang attribute which hreflang contained the two-letter code for the linked language. The hreflang attribute is not allowed on <li> elements. This attribute has been changed to data-drupal-language.

Before:

<ul class="links">
  <li hreflang="en" data-drupal-link-system-path="&lt;front&gt;"><a href="/" class="language-link" hreflang="en" data-drupal-link-system-path="&lt;front&gt;">English</a></li>
  <li hreflang="is" data-drupal-link-system-path="&lt;front&gt;"><a href="/is" class="language-link" hreflang="is" data-drupal-link-system-path="&lt;front&gt;">Icelandic</a></li>
</ul>

After:

<ul class="links">
  <li data-drupal-language="en" data-drupal-link-system-path="&lt;front&gt;"><a href="/" class="language-link" hreflang="en" data-drupal-link-system-path="&lt;front&gt;">English</a></li>
  <li data-drupal-language="is" data-drupal-link-system-path="&lt;front&gt;"><a href="/is" class="language-link" hreflang="is" data-drupal-link-system-path="&lt;front&gt;">Icelandic</a></li>
</ul>
