IFrame ID Target on IOS (IPhone)

I have a simple iframe on a page that should simply scroll to the anchor point #productDetailsAddToCartForm. This works great on desktop in Chrome, and IE. However when I check it on my IPhone it does not scroll to the ID defined in the below code. Any tips on how to fix this? Further I believe this worked before I updated my iOS to 8.

<iframe id="cartForm2" srch="http://example.com/index.php#productDetailsAddToCartForm"  style="height: 600px;width:250px;border:none;" overflow-y:hidden;" scrolling="no" onload="HideProgressBar();"></iframe>';
