Missing / Incorrect Definition

However current type definition is fractionalSecondDigits?: 0 | 1 | 2 | 3 | undefined;.

Sample Code

Intl.DateTimeFormat("en-US", { fractionalSecondDigits: 0 });
// RangeError: fractionalSecondDigits value is out of range.

This code throws RangeError on Chrome v101, Safari v15.4, Firefox v99 and Node.js v16,v17.
