Quinn Vault + Tristana Jump Bug

Hello, so obviously I was playing a ranked game as Quinn, laning against a Tristana.

In any case, I quickly discovered I couldn't vault off Tristana while her jump was up. Why? On multiple occasions, I would attempt to vault her to apply the mark. Tristana (blue side) would jump to the wall of the rift. I would, 100% of the time, end up from nearly the center of the lane to tri bush or turret range. I ALWAYS would end up 90 degrees to the right in respect to my starting position. Additionally, I believe she was able to flash before I hit her, but after her jump, to potentially extend this distance considerably (the one time she tried, she didn't flash full-length, but I believe the distance was still relevant.).

I've been playing league for a couple years now, and I recall a patch awhile back that declared these vault issues solved? I remember back before that patch when they were far more frequent, and this is the first I've seen of them in awhile. Then again, I have played against very few Tristana's until recently as well.
