This is the desired behaviour of the page. The following script is included on the page:

addEventListener("load", function()
{
setTimeout(updateLayout, 0);
}, false);
var currentWidth = 0;
function updateLayout()
{
if (window.innerWidth != currentWidth)
{
currentWidth = window.innerWidth;
var orient = currentWidth == 320 ? "profile" : "landscape";
document.body.setAttribute("orient", orient);
setTimeout(function()
{
window.scrollTo(0, 1);
}, 1000);
}
}
setInterval(updateLayout, 1000); 

Basically any time the width of the browser window changes it will jump back to the top. This happens in desktop firefox as well, if you load the page with the Fennec UA, then scroll down, and resize the width of your browser window.

While I agree it's annoying, this happens for all mobile browsers. (In theory the developers thought this was a good idea, based on the code). 

Closing as WONTFIX, but feel free to reopen or contact the site if someone feels this would be a good use of their time.
