Try my committed code and let me know if you have any more issues.
I tried with a necro casting Ancient: Seduction of Chaos (497
and a Shaman casting Ancient: Chaotic Pain (4979). I did not get any can't attack messages from pets and nothing showing up in the extended target window that shouldn't have, while using RoF.
There are probably other instances where this can happen, and I will continue to try to find them, but hopefully that helps.
