//
// The browser is allowed to clamp resulting values to the nearest multiple of
// the [step] value:
//
// When the element is suffering from a step mismatch, the user agent may
// round the element's value to the nearest number for which the element
// would not suffer from a step mismatch. If there are two such numbers,
// user agents are encouraged to pick the one nearest positive infinity.
//
// WebKit seesm to perform this clamping when stepping from the UI, but not
// from the API.
