jquery - fullpage.js one section slider scrollbar autoscroll toTop issue when scrollOverflow:false -

as when disable scrolloverflow in mobile device use normal scroll more smoother , slider auto scroll top when drag scrollbar down ..

the effect see snippet below , try viewing in small width window, scroll anyplace , stop, scrollbar autoscroll top itself.
option settings or methods can use fix this?

$('#fullpage').fullpage({           paddingtop: '10px',    verticalcentered: false,    slidesnavigation: true,    slidesnavposition: 'bottom',    css3: true,    scrolloverflow: false,    autoscrolling: false,    controlarrows: false,  });

.slideone {    background-color: #99ccff;  }  .slidetwo {    background-color: #ff66ff;  }  .slidethree {    background-color: #00cc99;  }  /* overriding styling when turning down slimscroll overflow option */    .fp-section,  .fp-slide,  .fp-tablecell {    height: auto !important;  }
