[gameplay] Pink wards can spot Evelynn over walls

Just played a game where it was really close, I come up behind them and then it tells me i'm spotted even though no pink wards are in sight. Sejuani ults and they kill me, but before they kill me I place my trinket ward into the brush over the wall and see there is a pink ward. Even though the pink ward does not have direct vision of me it still spotted me. Here's a video of the bug with reproduction steps: https://www.youtube.com/watch?v=FL-9ZlY6el4

I don't know if this is intended but with the new mandrake ward coming out maybe this should be fixed.
