It's not, actually.  In Firefox, an event will bubble from a Window to 
some object in the browser UI associated with that Window.  This object 
is the same for a page and all its subframes.

What this object is is effectively an implementation detail.

Note that we plan to keep this behavior as we move to a multi-process 
architecture, at which point the event will effectively bubble across 
the process boundary.
