Language Toggle not visible on mobile when using the "Internet" as base theme.

Copied from: https://github.com/wet-boew/wet-boew-drupal/issues/1823

I have noticed that when I do a base Drupal WxT install ( v4.6 ) - and I set the base theme to be "Internet" - when I shrink to mobile and click on the hamburger to open up the menu - the menu that was at the top right corner of the site, including the language toggle, is not in the mobile view.

Is this something that was done by design, or possibly something that was missed ( im assuming the later of the 2 ). It seems to be there in all other variations of the base themes.

Thanks.
