Falsely matching recurring days

[pacobalt]

When I want to match a day with e.g. the last day of a month that has only 30 days, the method "matches" will return a false "true"

const rc = moment("2017-04-30").recur().every(1,"months");
console.log(rc.matches("05/30/2017")); //true
console.log(rc.matches("05/31/2017")); //true

Is this a bug? Or am I doing something wrong here? This is only happening, if the recurring start date is the last of a 30 day month or if we choose the last of February and match it with any other day of the month higher than 28.

This should only be happening on the dayOfMonth calendar interval (where it assumes that you want the last day of the month if the date you select is the last day of the month). We should make this an explicit option, though, and not have it happen by default...

Marking this as a bug to be investigated.
