I played a game as Fiora where I ulted a Kha'zix as he was using his ult. After he became unstealthed I noticed that he took 0 damage from my ultimate. I haven't played much Fiora so I'm not sure if this happens with all stealths, but I know she had bugs with her ult involving stealths before and I think this might just be something that wasn't fixed with the other bugs.

I do think that's odd. I had it happen to me recently as well.
Especially when around that time, I used Fiora's ult on a low HP LeBlanc who still had her passive and still stuck on her through LeBlanc's passive stealth.
The only skill I can think of that should break it (in a 1v1 setting) is Shaco's ultimate due to the coding. There shouldn't be any other skill/item that breaks it.
