I have been filing bugs in the answer editors on forum. The bugs are still here, for example see this thread, http://www.c-sharpcorner.com/forums/i-have-question-asp-net-mvc-on-click-on-button-send-email (I am adding two new lines, but by the end I post it, they will be removed.) You can see how white spaces are removed, how extra lines are removed and it causes a really annoying look of the answer which gets posted. Fix that. Also, the error comes when the post is submitted, before that there is no problem in edit mode.
