What about the part that says "In this step, invoke means to run the jump to a
code entry-point algorithm"?

Ok, but if you do:

foo.addEventListener("evt", funcFromFrame2)

I'm pretty sure Gecko will use frame2 as the entry settings object, even though
the implicit conversion to Function theoretically happens in the scope of
frame1.
