In fact this is the case but it's still not scrolling properly for me.  It is
hitting the <HTML> node within the frame, which is what you describe should
happen.  However it still sometimes sends the scroll up to the parent frame. 
Testcase:

<iframe src="text.html">  (positioned as described

text.html:
this is a test this is a test this is a test<br>
this is a test this is a test this is a test<br>
this is a test this is a test this is a test<br>
this is a test this is a test this is a test<br>
(repeated many times)

I think maybe I have misdiagnosed the problem though.  it doesn't -always-
scroll the wrong frame.  I think it has to do with over-dragging (ie: dragging
past the edge of the frame during scroll)
