(N.B. this is similar to bug #6281)

a safari user created a test site containing three frames, where one frame
(main.htm) sets the location of the two other frames through javascript (e.g.
window.parent.frame1.location=...).  apparently safari is the only browser that
(occasionally?) fails to display the content in these two frames.  the full
discussion is located here:

i'm guessing this is due to security restrictions, but i've verified that
firefox 1.5.0.1, camino 1.0rc1, and opera 9.0pre2 all allow this cross-frame
javascript code.  both the latest safari stable and ToT fail.

i'm attaching a slightly reduced test-case of the problem.
