parseDuration() seconds constraint

[crazko]

parseDuration() of @internationalized/date sets boundaries to the numbers that are being parsed.

Seconds are set to max 59 which prevents from parsing duration with fractional seconds above this limit:

const duration = "PT59.123789456S";
const result = parseDuration(duration); // throws: Invalid ISO 8601 Duration string: PT59.123789456S

While testing this with Temporal (polyfill) results in milli/micro/nano seconds:

const result = Temporal.Duration.from(duration);

// result.seconds - 59
// result.milliseconds - 123
// result.microseconds - 789
// result.nanoseconds - 456

Is this a desired behavior? Shouldn't it be allowed to have any decimal seconds value up to the 60?

Thanks for the feedback and the CodeSandbox reproduction. parseDuration() from @internationalized/date should match the behavior of Temporal.Duration. This would be a good first issue for someone to contribute as a PR.
