That's probably good news. I'll admit that I wish one widget handled all that, but that may be asking too much.

I had noticed that HTML could be busted in the same way that you can do it in the post editor:

You go into text mode in the editor, stick in some HTML, and save. So far, good. Then you go back in for some reason, and you're in Visual mode (or switch to it). If you happen to save then, whether changing something or not, the HTML (or shortcode, etc.) might bust.

Given that both contexts use Tiny, this is no surprise.
