Fix to CR 6673601 disabled background erasing in all EmbeddedFrame. A safer, more targeted fix for Plugin embedded frame is found. Instead of unconditionally setting disableEraseBackground in EmbeddedFrame ctor, you should better override addNotify() method in Java Plugin embedded frames (like WNetscapeEmbeddedFrame) and set this property there. This method - addNotify() - is called prior the frame's peer is created.
