     the top identity navbar and footer areas
  2. Log in and navigate to a user's settings page: '/profile/settings'

     preference from the dropdown. Select something other than english,
     and then click the 'Update Settings' button to confirm
  4. Across the header or footer of the page click the 'Help' link to open
     the modal
  5. Ensure the text displayed is rendered in your currently set
     language preference
  6. Repeat previous steps to confirm that the modal text updates properly
     after selecting a new language preference
