             Summary: Incorrect window.orientation value for portrait-only apps after returning from landscape mode (and vice versa) on iOS
                 Key: CB-3065
                 URL: https://issues.apache.org/jira/browse/CB-3065
             Project: Apache Cordova
          Issue Type: Bug
          Components: iOS
    Affects Versions: 2.6.0
         Environment: Mac OS X 10.7.5, Darwin Kernel Version 11.4.2;
XCode 4.6.1
iOS 5.1-6.1 

            Reporter: Aleksey Yashchenko

            Priority: Minor


When changing orientation in portrait only app (e.g. by opening youtube video link in InAppBrowser and watching video in landscape mode) window.orientation have invalid value that affects many UI rendering code/styles.

Steps to reproduce:
- compose HTML with two buttons, 1: onClick='alert(window.orientation)', 2:onClick="window.open('....://www.youtube.com/watch?v=xxxxx', '_blank');
- compile this resource to portrait only app (set UISupportedInterfaceOrientations to UIInterfaceOrientationPortrait in Info.plist)
- run app
- check orientation with first button, in portrait mode its 0
- push the second button, start youtube video, rotate device to landscape mode
- when in landscape mode press Done in YT video player and in InAppBrowser
- with first button check orientation its value -90/90

Described effect causes glitches and partial page rendering in several UI frameworks. Looks like web view gets incorrect orientation change even sequence why change itself is blocked by Info.plist setting.
