iOS Webview goback doesn't work in iframe?

[binjaja]

I have an page, called MyPage.html loaded into a UIWebview that uses an iframe.
When the user is inside the iframe, they may click many links. At some point they select “goback”.
I expect the webview to go back to the previous page in the iframe but it doesn’t. Instead it goes back to the page that was loaded before MyPage.html.

When I run the same test on Safari, it acts correctly, in that the user is able to use the back/forward buttons to move within the iframe.I was hoping that it would work the same way with UIWebView. Isn’t this a bug in “goback” ??
