Rémi Verschelde bfd5e09879 Range: Fix cases where max was set to or below min value 
It will now raise an error whenever this happens so that we can fix
these situations. `max == min` is not allowed as it could lead to
divisions by zero in ratios, and `max < min` doesn't make much sense.

Fixes #33907.
