WordPress Twenty Seventeen Front Page sections scroll effect not working on mobile

I have a wordpress site and using Twenty Seventeen theme, I like the scrolling feature on the Front Page Sections, just like in this demo:


Now I am trying to get that scrolling feature to work on mobile, however when I look at the CSS I found this

.background-fixed .panel-image {
   background-attachment: fixed;

But I know background-attachment does not work very well on mobile. Does anyone know of a work around, everything I have found and tried online does not work.
