Shen Dash Jax Jump Bug

Was playing ranked yesterday, and for some reason we had a jungle. He did really well and was counter jungling. Mid to Late game was stealing enemy jungler red buff. He took red and was recalling inside red buff area. We had good vision of the area around there so saw the coming. He didn't have time to run anywhere once he realized the enemies position. So being he was waiting on the cooldown on his dash. As soon as it came up he dashed over red wall (the big log) towards the river opening by raptors on the purple side. Well over the wall, got jumped on by Jax and died while over the wall, but there was no physical contact. Jax jumped where Shen was before the dash. I wish I would have recorded it. But the pretty much jumped onto the now nothing and no one still inside red buff, and got the kill so late after dashed over the wall. Everyone blew up chat after, cause we all knew got cheated. Up vote appreciated so it is more likely Riot sees and fixes this. Please fix this Riot. Thanks for reading! :D
