Blue trinket blocks pathing

I just played a game where I bought the blue trinket upgrade. I used it inside the enemy red buff brush. I then rightclicked to get to baron, which made me autopath right over my blue trinket ward thingy. I randomly got stuck between it and the wall to redbuff. I just stopped walking and my autopath got cancled. I spammed right click on baron, but it got cancled immediatly again. I needed to manually walk around the ward in order to get out of it. So walking backwards got me unstuck. I dont think that this is working as intended, since the ward shouldnt have a hitbox, that blocks me.

Will try again if I get lvl 9 blue trinket and can maybe provide some proof.
