tempCanvas glitches out using "take a photo" on iOS (8.1.2 at least)

The temporary canvas generated for resizing prior to confirming the crop doesn't work on iOS 8.1.2 (not sure if it worked previously).

The demo JSBIN seems almost up to date but I've updated it just in case: http://jsbin.com/liqehiyuyu/3/edit

If you visit the JSBIN page on an iPhone and use the "take a photo" (as opposed to "select from library"). The canvas glitches out, not allowing you to slide the image right. Also, the axis are reversed x-axis touch events trigger y-axis move and vice-versa.

I can't really test on an older version of iOS, is it already known to work there? Note that this doesn't seem to be an issue with photos selected from camera roll / library.
