Videos in StageWebView Playing Back at Double Size Under iOS 8

We're having an issue with videos in a StageWebView under iOS 8. Videos playing in a StageWebView control are playing at double size on iOS 8, resulting in the video appearing to be chopped off (see screen shot below).

We are using a StageWebView and calling the .loadURL(videoPath). Previously the video has always been sized to the viewport of the StageWebView control.

public var webView:StageWebView;

webView.viewPort = new Rectangle(this.x,this.y,374,221);

webView.loadURL(<<our file path>>);

Has anyone experienced this or have any idea what's going on? Thank you for your help.
