IMHO we need to verify first if this is really a webkit's bug or it's  
actually Emacs own problems. The simplest way is to write some toy  
program to reproduce the issue without involving Emacs.

From the bug description, I saw Po mentioned that he "can't get video  
to play in a WebKitWebView attached to a GtkOffscreenWindow", it would  
be better to elaborate how the buggy code is written and see if we can  
extract those part into independent sample program and send it to the  
webkit team.

Thanks.
