Using Google Chrome's DevTools Mobile Emulation, it seems that the touch scroll is not working.
See this test: http://codepen.io/dstj/pen/Datcw
Scrolling works on both an iPad 3's Safari and Android 4.2' Chrome, but does not work in Google DevTools with Touch Screen Emulation.
Another difference I see is that scrollbars appear on DevTools, but not on tablets…
Any ideas why?
Note: Using Chrome Version 33.0.1750.154 m

When it happened to me, I closed the tab and launched again. It fixed it.
