I am trying to add web links in the caption descriptions of my story map. It allows me to initially add it and successfully save, but as I add others, it fails and seems to add a "tabindex =-1" command to my html string. The error message is "Save failed due to an invalid html tag in a name or description". When I remove this, it saves fine, but it returns automatically and then fails again. Why does it behave this way? How can I get it to permanently not add this command? Is there another way to add web links to my caption descriptions?
