Background image wont export from Kendo.
Is there a way to get the background image to export to the png file.
I am not clear why the background image won't export.

exportdrawing.zip

This is a bit more complex than original post. The background in original post would not export because of cross domain which is documented. However, I am unable to export a background that is local if it is set via angular. An updated example of the failed export background is attached.
