A gif to explain:
As you can see, clicking 'discard' under an answer whilst editing a post inline causes the tags in the edit to also be removed.
I presume this is because the click handler for the 'discard' button is the same for questions and answers; if it is a question, it does need to delete the tags. But this doesn't work for answers - please can a new handler be made/or the existing one edited to check whether the discard is for a question or answer, and decide whether the tags need to be discarded or not.
I understand this is a rare case - but it looks easy to fix... if it is, please can it be fixed? :)
