It appears that the oncontextmenu event won't get previewed correctly in all
circumstances. I've entered issue 2895 to this effect.
If the code you mention above is no longer working, it is probably because
the oncontextmenu property is being overwritten by sinkEvents(). Try moving
it to after sinkEvents() is called on the element -- I believe that should
work for now.
