Hi, could we please, please, please, add one of those red boldfaced "Are you sure? y/n" confirmation dialogs when someone hits "Cancel" while typing a reply?

I use the site on my phone, and I keep fat-fingering that button almost all the way through typing long replies and POOF there goes everything and there's no possible way to get it back.

Thanks to anyone who could change this—I'm guessing that it's doable, because that dialog does happen in other places, including some where it seems entirely unnecessary (e.g., editing a title? I don't get it)
