iPhone In-Call Status Bar not resizing 'More' View

When you toggle the In-Call Status Bar with the moreNavigatio开发者_StackOverflow中文版nController displayed in a UITabBarController, the moreNavigationController does not resize like other views.

Is this something I can change in code or is it a bug in the SDK?

I'm using the iOS 4.2 SDK.

Under normal circumstances, the in-call status bar cannot simply appear while your app is running. The fact that you can do this in the Simulator is completely artificial.
