Issue with StageWebView in WindowedApplication

I have observed a potential bug in AIR 31. I have created an AIR WindowApplication for the desktop. Then I create a StageWebView in a separate Window class. However when I load web content the html content is displayed in the WindowApplication frame. This only seems to happen under MS Windows. Under OS X the web content is shown in the Window class frame.

Steps to recreate:

• Create a WindowApplication.
• Create a Window class with a StageWebView (native true).
• Open the Window class and display a web page.
• Under OS X this works. ie the web content is shown in the Window class.
• However under MS Windows the web content is shown in WindowApplication frame.
