Anchor scrolling on mobile

Hello,

I’ve created multi-color-section homepage using tutorial http://kriesi.at/documentation/enfold/add-anchors-to-your-page-for-single-page-navigation/. For desktop media it works fine but when I switch to the mobile resolution, the scrolling does not scrolls properly. For the testing purpose I prepared simple page with 3 color sections http://www.mykarma.guru/scroll-test/.
I have already tried many solutions but the result was always the same.

Thanks for help!
