Problems with midnight on addWorkingTime

[giacomomichelon-centropaghe]

Hi,
i have an issue with the following situation:

    describe('Midnight problems', function () {

        it('Add times between days', function () {

            moment.locale('en', {
                workinghours: {
                    0: null,
                    1: ['16:00:00', '24:00:00'],
                    2: ['16:00:00', '24:00:00'],
                    3: ['16:00:00', '24:00:00'],
                    4: ['16:00:00', '24:00:00'],
                    5: ['16:00:00', '24:00:00'],
                    6: null
                }
            });

            moment('2022-03-23T22:00:00.000').addWorkingTime(121, 'minutes').format(full).should.equal('2022-03-24 16:01:00.000');

        });
        
    });

this is a test that i added to show the issue, if you try to run it it goes on an infinite loop,

i have found a fix to that:

function addUnit(unit) {
    return function (n, d) {
        if (!d.isWorkingTime()) {
            d = d.nextWorkingTime();
        }
        var i = 0;
        while (n > 0) {
            var segment = openingTimes(d)[i];
            if (!segment || d.isBefore(segment[0])) {
                i = 0;
                d = d.nextWorkingTime();
                continue;
            }
            if (d.isAfter(segment[1])) {
                i++;
                continue;
            }
            var jump = segment[1].diff(d, unit);
            if (jump > n) {
              jump = n;
            }
            if (jump < 1) {
              jump = 1;
            }
            var then = d.clone().add(jump, unit);
            n -= jump;
            if (then.isSameOrBefore(segment[1])) {
                d = d.add(jump, unit);
            } else {
                var next = then.nextWorkingTime();
                var diff = then.diff(segment[1], unit, true);
                d = next.add(diff,unit);
            }
        }
        return d;
    };
}

the fix is right before the first "continue" statement, i would like to push the fix, but i am unable to do that
