This "cross width" field is not even important. I think I saw it disappearing before, but I keep it only because it is there since the beginning. I remember only once that someone needed this option, otherwise I don't even recommend to use it. This is one of those things that I would remove if it depends only on me 🙂
Do you have example of the "... limits" block that shows the problem? This block is more complicated 🙂
