Slider and Zooming Issues

[skibulk]

I downloaded your master package and opened index.html. The slider does not drag, but if I click on it, it will advance to where I clicked. When I use zoom, the canvas seems to be duplicated each time, leaving behind the original canvas and displaying the zoomed canvas over top. These issues occur in both IE Edge and Chrome. I also tried running the package in WAMP, but no luck. No errors are reported in the Chrome Console.
