FIX: Empty inline BBCodes were broken (#18276) 

Upgrading to Markdown.it v13 broke empty inline BBCodes. This works around the problem by adding an empty token before a closing token if the previous token was a BBCode token.

It also removes the unused `jump` attribute which was removed in Markdown.it v12.3
