I was deleting multiple msgs in a
Drafts folder and noticed that after I
opened the draft msg and
Discard-ed it, the
Drafts folder message counter does not update. Not a show-stopper but it seems that the counter should update immediately.
See below (after I had opened and
Discard-ed the last remaining msg in the
Draft folder.)

Naturally, after I opened the folder once again, the count updated.
If we
Discard a draft msg directly from the folder list (i.e., don't open the message) then the counter updates immediately.
