description: Checks the handling of plural unit arguments to Intl.RelativeTimeFormat.prototype.formatToParts().
info: |
FormatRelativeTimeToParts ( relativeTimeFormat, value, unit )
3. Let n be 0.
4. For each part in parts, do:
a. Let O be ObjectCreate(%ObjectPrototype%).
b. Perform ! CreateDataPropertyOrThrow(O, "type", part.[[Type]]).
c. Perform ! CreateDataPropertyOrThrow(O, "value", part.[[Value]]).
d. If part has a [[Unit]] field,
i. Perform ! CreateDataPropertyOrThrow(O, "unit", part.[[Unit]]).
e. Perform ! CreateDataPropertyOrThrow(result, ! ToString(n), O).
f. Increment n by 1.
