Able to smite tryndamere through his ult, I have proof as well (lolking replay)!

I was playing trydamere and at exactly 32:25, hecarim smited me and killed me. I was only 2.5 seconds into my ult. This bug literally makes tryndamere USELESS. Why has this not been hotfixed? Hecarim had "Skirmishers Sabre".
Attached is a lolking replay and if you go to 32:20 and watch for 10 seconds while focused on tryndamere, you can see I indeed get smited through my ultimate.
Please fix this asap.
