Renekton can E over Jinx traps

I was playing a ranked game earlier and the enemy renekton was able to E right over my traps. Since I was ADC and it's Renekton, I died because of this, but could've killed him if he was snared. Instead he came right on top of me without proccing a single trap. I had placed the traps about 1.5 seconds earlier and therefore they were armed so it should've stunned him.
