Cannot add exrule after querying rruleset

[jofmi]

If I apply exrule after querying the rruleset, the exrule will not be applied.

Here is an example:

const rruleSet = new RRuleSet();

// Add a rrule to rruleSet
rruleSet.rrule(
  new RRule({
    freq: RRule.MONTHLY,
    count: 5,
    dtstart: datetime(2012, 2, 1, 10, 30),
  }),
);

// Querying the rruleset before applying the exrule
console.log("Before", rruleSet.all());

// Add a exclusion rrule to rruleSet
rruleSet.exrule(
  new RRule({
    freq: RRule.MONTHLY,
    count: 2,
    dtstart: datetime(2012, 3, 1, 10, 30),
  }),
);

// If the ruleset is queried above, this will show 5 dates (exrule not applied)
// If the ruleset is NOT queried above, this will show 3 dates (exrule applied)
console.log("After", rruleSet.all());

Affirmative. I ran into the same issue (even using the expample for exdate/rule from the README), only that I dind't understand that this due to the prior querring (so thx @jofmi, this was causing me some headage).
