Beacon lights dissapearing when you look at them from a certain angle

I was trying to look ate the beacon lights they didnt show up at a certain angle
I expected to see the beacon lighs from every angle

I loked at the beacon lights facing forward and could not see the lights, if i looked just a bid downwards the lights appeared

Steps to Reproduce:
1. Put all the coloured beacons side by side + the regular beacon
2. Go increse your Y elevetion till you dont see the beacon blocks
3. Look straight forward or straight up from any distance from the beacons => not see the lights
4. Look a bit downwards and the lighs reappear
