possible bug with poppy.

I was playing a match as poppy and had banshees and homeguard boots on the spawn platform I found cait in our base and right clicked her then flash rd to ult her. it was successful. my ult triggered and was around cait but somehow i was still knocked up and ulted by blitz, rooted by maokai, ulted by annie, and feared by fiddle. i died within 2 seconds and lost the game because of this. the link is of my match history i dont know if it matters.
