FYI, I have updated docs for this in preparation for FF84:
- Intl.DateTimeFormat() constructor - added
fractionalSecondDigitsto syntax - Interactive example will show some use of the options, including
fractionalSecondDigits - For more information on this docs work see https://github.com/mdn/sprints/issues/3897
Questions:
- ON testing fractionalSecondDigits appears to truncate the fractional part rather than rounding - is this correct?
- dateStyle and timeStyle do not appear to be able to work in conjunction with the other options (i.e. you can't specify a dateStyle and then use hour, second, fractionalSecondDigits etc to specify the time. Is that correct?

Cool, thanks!
Questions:

Yes, the property is spec'ed to truncate its input.
- dateStyle and timeStyle do not appear to be able to work in conjunction with the other options (i.e. you can't specify a dateStyle and then use hour, second, fractionalSecondDigits etc to specify the time. Is that correct?
Yes, dateStyle and timeStyle are currently all or nothing. This is a restriction based on the underlying CLDR data (https://unicode-org.atlassian.net/browse/CLDR-13425).
