iframe not scrolling on iPad

[hsog]

Excellent slider but I need to put an iframe onto a slide and use on an iPad. When I do this all seems to work fine except the iframe doesn't scroll. My usual approach is to use the method explained at
https://davidwalsh.name/demo/scroll-iframes-ios.php
but that doesn't seem to work for me either.
Oddly, it does seem to work if it is on the page that is being loaded when AnthingSlider first loads but then, when the slide transitions in it stops working.

Hi @hsog!

Please modify this demo to duplicate the problem. I don't own an iPad anymore, so I may not be able to get you an answer quickly.
