That still seems like a surprising behavior (and it entirely
disables step constraints in a peculiar set of cases).

It would seem better to either:

 * infer the step base from the minimum whenever there is a minimum,
   or

 * when inferring the step base from the default value (the value
   content attribute), apply the minimum and maximum to the default
   value
