When the the screen is resized to the mobile size, the user menu and the language menu is to move into the side panel with the other navigation elements, leaving the messaging and notification icons behind.

Talking with the integration team, adding the mobile navigation html and having it hidden is fine, but we have to be aware that behat looks for the first element to "click" regardless of whether it is hidden or not.

Edit from Matt ~ This may no longer be required as the usermenu may remain in the navbar and the language menu is in the usermenu
