I tried a few methods of having the plan description area announce something, but nothing seemed to be working. aria-describedby seems like it would be a fit here, however there isn't an element that's tab-able before you get to the tinymce editor. Perhaps making the "?" be tabbable might help, if it isn't redundant with the descriptions already happening when you go into inputs like the plan title?
