WPEView in Fragment crashes after navigating to other Fragment

[zhani]

Crash happens when WPEView is used in fragment and navigation from WPEView fragment to some other fragment happens.

Root cause is in RendererASurfaceTransaction. Transaction completed callback is posted to ui thread and meanwhile underlying page has been destroyed because fragment is gone

I'm having a similar Issue when close the Activity that holds the WPEView on v0.1.2 :
