"Undying Rage" isn't as "Undying" as it Sounds

I just got out of a game in which I played Tryndamere as a top laner against a Fiora and her jungler Warwick (I bet you can already tell where this is going). About midway through the game, I noticed that I kept dying... and dying... and dying from what seemed like a interruption of my ult. After a few times of this happening, I noticed in the Death Details bar that a significant portion (or at least, enough to be listed) of Warwick's damage to me came from one of the new jungle items. I didn't recall him using that ability on me, so I dismissed it as my not paying attention to the effect details, until a few minutes later, my Undying Rage was stopped after only a second or two of being in effect, and I died. I'm not sure if this is actually due to the modifications made to smite through the new jungle items, but my friends and I thought that it was something worth reporting, just to see if it was truly an issue, instead of an isolated incident.

Please respond to the poll below so Riot knows if this is worth looking into or not.
