Jhin traps and teem shrooms triggering multiple times

I just played an intro bot game for missions and noticed that one trap/shroom will be triggered ~10 times and do damage every time. I don't know if this is only happening in this specific mode/game but I couldnt replay this in training mode.

Sorry for the bad quality of the video I was shooting with one hand and playing with another.

edit: i can recreate this bug again in intro bot games but not other modes. https://youtu.be/whiOGRPpCxQ Like this.

The number of triggers depends on how long enemies stand on the trap after the first trigger.
