Agreed. It appears it's the author's choice of text editor that apparently needs to be less smart. If you chose an editor that doesn't let you configure something so basic, that's on you.
This isn't about a primary text editors, it's about all the other ones you're forced to use. I use uncountably many text editors daily, and I don't get a choice in most of them. Like the one I'm using right now to type this comment! Fortunately <textarea> is very sane.
