Disable pull to refresh on all sites.

Chrome's pull to refresh is annoying. Have it disabled with:

body{
overscroll-behavior-y:none;

}

Then make the 0 button able to be pulled down to refresh the page.

Scrolling up on ZeroHello for instance sometimes causes a page refresh and I find this problem unavoidable until the CSS above is added.

It's a mobile device problem.

No files, tests, or entry points are named. Start by locating the CSS applied across ZeroHello and the mobile handling for the 0 button, then verify the behavior on a mobile device: ordinary page scrolling should not trigger pull-to-refresh, while pulling the 0 button should refresh the page.
