Toast Notification Icon not displayed on WebOS 3.0

[Rapsoulis]

Although the sendToast() was working properly with WebOS 2.0, it is not working with WeboOS 3.0! The icon is never displayed in WebOS 3! Neither if you grab it from your resources and it's converted, nor when you save a BASE64 image as a string value in string resources. I've tried all possible ways, but none works.

I believe that either the Base64 is no longer supported by WebOS 3.0, or the whole payload is wrong.
