Description

Occasionally the entire web view is cleared. White screen. Plugins and other components remain unaffected. Observed when playing background audio (via CDVSound), going to background, and running other apps. Audio continues uninterrupted, but bringing the app to foreground reveals white screen.

It appears to be related to an issue with the XPC connection being lost between the app and the wkwebview (log in XCode mentioned the XPC connection being interrupted). (see also: http://stackoverflow.com/questions/25854143/wkwebview-intermittent-blank-screen-issue )

The plugin should detect if the WKWebView has reset and reload the app.
