 because it doesn't have any fonts whitelisted that include all dingbats?
 Or is the whitelisted font that allows dingbats to work not working for
 some reason? Does this have to do with #16739 at all?

 Hi vegansalad,

 Thanks for reporting this problem. Please keep it all comments on it on
 one ticket, though! :) I think #18364 is probably the best place for that
 discussion.
