I submitted the difference between the 1.7.4 and recent 1.8a5 builds as bug 266850.

missed to adjust URLs in JS

Attachment: further reduced testcase

Further reduced testcase for the submenu positioning problem (still involves
three nested tables; no JS required).
In Safary (and presumably Win/IE as well), the third table (containing the
links) is rendered undernieth the top-level table. In Firefox, it overlapps it.

I don't have time to attach screenshots - sorry.

Layout bugs like this tend to be dupes, so not confirming yet. CC'ing bzbarsky
instead.
Also added some technical info to summary.

Uri, if there is no equivalent testcase on bug 63895, could you add this one there?

[Uri Bernstein]

No, this is pretty much equivalent to testcase #1 in bug 63895. 
The outermost table in my testcase is actually unnecessary, and the innermost
one can be replaced by a div.
