title: WebView scrolls itself
body: <p>I've got a UITextField added as a subview to a UIWebView that acts as an address bar for a browser. But it's behaving rather strangely, because when the field begins editing the webView automatically scrolls itself to about (-40, 0) and I can't figure out why. I've already tried calling [webView setContentOffset] to counteract this behavior, but that doesn't work for some reason (yes I have the delegate connected). Am I missing something?</p>
