Is there any way to get the oauth2/authorize page to put padding around the login UI?
My app's UI looks like this (I'm not using the iOS SDKs, I'm using the REST API directly, so that I can present the auth interface in a custom way):

The popover contains a plain UIWebView. However wide I make the popover / webview, the email and password fields size to fit the width and the "sign in" button right-aligns without any padding, so they end up hard against the edges. Is this by design?
