Trial Chamber’s Assembly dispenser/pressure plate trap does not damage the player

The Bug:

 

A bit similar to MC-275804, in the Assembly room within Trial Chambers, there are dispenser traps you can activate by stepping on a pressure plate.

 

However, at least in Java edition, these traps do not work and fly right through the player, leading to them being inconsequential.

 

Expected Result:

Stepping on these pressure plate traps would harm make a projectile hit me, instead they pass through
