fixes UXS-87
flag = featured_help_links

test plan:
 - make sure a help link is tagged as NEW
 - using a SR, open the help menu
 - navigate to the link tagged as NEW
 - the SR should read the link title, the fact
   that the link is tagged as NEW, and then the
   link description
 - it should be obvious which link is the tagged one
