can't copy the input field value inside iframe on iOS5
===

I can't copy input field value.

I tried this steps.

 1. focus input field
 2. hold and tap select all
 3. tap copy

http://jsfiddle.net/wYMKE/4/　can copy text. (not load Zepto.js)

http://jsfiddle.net/wYMKE/5/　can't copy text. (load Zepto.js)

I think the reason lies with Zepto.

Do you know anything about that?
