byweekday undefined has different behavior than empty array

[SinBirb]

If this is expected behavior, please document it. However, I would expect an empty array to be treated the same way as not giving the option or at least .count() being 0. But if byweekday == [], then all days are in the rrule, which is definitely not obvious.

• Verify that you've looked through existing issues for duplicates before
  creating a new one
• Code sample reproducing the issue. Be sure to include all input values you
  are using such as the exact RRule string and dates.

const dtstart = new Date(Date.UTC(2023, 8, 15, 3, 0, 0));
const until = new Date(Date.UTC(2023, 8, 22, 3, 0, 0));
const rule1 = new RRule({
    freq: RRule.WEEKLY,
    dtstart,
    until,
    interval: 1,
    byweekday: []
});
const rule2 = new RRule({
    freq: RRule.WEEKLY,
    dtstart,
    until,
    interval: 1
});
console.log(rule2.count() == rule1.count());

• Expected output
  true
• Actual output
  false
• The version of rrule you are using
  2.7.1
• Your operating system
  Arch Linux
• Your local timezone (run $ date from the command line
  of the machine showing the bug)
  CEST
