Using background-position instead of background-size

[subproject22]

In v4 using custom size for background, like bg-[4px_4px] generates background-position instead.

Hey! You need a type-hint here otherwise we can't set the right property, see: https://tailwindcss.com/docs/background-size#using-a-custom-value

bg-[length:4px_4px]

Thanks. lenght is missleading, because I've literally wanted height. size hint worked!
