Disable scroll while waiting to for scroll selection animation to complete

I'm trying to make customize section-scroll where scroll event is disabled while animation is in motion. I tried with overflow hidden and other similar functions to apply while scroll animation is in progress but no luck.

JS fiddle example

CSS

.stop-scrolling {
  height: 100%;
  overflow: hidden;
}

JS example:

$('html').on('wheel', function(event) {
  if (event.originalEvent.deltaY > 0) {
//scroll down
    counter++;


    $('body').addClass('stop-scrolling');
    console.log("Start animacije");
    setTimeout(function () {
      $('body.stop-scrolling').removeClass('stop-scrolling');
      console.log("End animation");
    }, 800);



    if (!(counter > maxSections)) {
      $('html, body').animate({
        scrollTop: $( $("#sect-"+counter) ).offset().top
      }, 800);
    }

  } else {
//scroll up
    counter--;


    $('body').addClass('stop-scrolling');
    console.log("Start animation");
    setTimeout(function () {
      $('body.stop-scrolling').removeClass('stop-scrolling');
      console.log("End animation");
    }, 800);


    if (!(counter < 1)) {
      $('html, body').animate({
        scrollTop: $( $("#sect-"+counter) ).offset().top
      }, 800);
    }

  }

  if (counter <= 0) {
    counter = 1;
  }
  else if (counter >= 3) {
    counter = maxSections;
  }

  console.log(counter);
});

If you scroll while animation is in progress, scroll will continue until you reach end of sections.

Is possible to disable scroll event while animation is in progress?
