What were you doing:
When I drag a note onto a subtag in sidebar (e.g. #project/sales) , the tag is appended to the note correctly. However when I want to take this action back (Edit→Undo), only subtag is removed and parent tag stays (in this case the note has still tag #project).Only subtag is removed. I believe it is because of how undo is implemented when adding a tag textually when editing the note. In that case, it makes a sense. But in this case of dragging a note, it is confusing IMO - the whole tag (parent tag and subtag) should be removed from the note when undoing the action.
