You should be able to do this in the PopupMessage::MessageBubble ctor, since
GetBubbleFrameView() is a protected member of its BubbleDelegateView superclass.
Then you don't need to modify the widely used bubble implementation for a less
common setting.

Well - it appears that you have never tried this before because changing the
offset post creation has several implications. But I was able to find a (in my
view not so clean) way around it and to remove this function. For the sake of
clarity and simplicity I would strongly recommend to add this function though.

Removed as requested.
