comparator something I guess

So I was setting up a comparator to a chest and I accidentally right clicked on it... (BTW im not sure it only affect that version of mc)

but what I noticed is that it flashed for 1 tick (I think) but only when I turned the front torch off

1.power a comparator with an inventory (MUST BE A CHEST OR SOMETHING LIKE A SHULKER BOX
2.start flicking the front torch on and off
3.notice the back torches deactivate for 1 frame

also idk if it is a bug but I have been having update issues on comprators like not detecting anything until I update it

also i dont think this is really something but chests disspapear if you go far enough away
