The bug
The beacon's model's glass doesn't cull against other beacons, however, unlike the glass block. Considering a glass block does cull itself, I am in the personal belief a beacon's glass should cull itself too. (Glass blocks and beacon glass should also cull each other if it should look completely right, but I'll take it as fixed as long as the beacon just culls itself.)
How to reproduce
Place a beacon right beside another beacon
→ Notice the glass between the beacons being visible
Note
Modifying the JSON block model of the beacon to have the glass cull will only cull the glass against solid opaque blocks (which in my opinion it also should cull against), not other beacons.

How is a pretty big inconsistency between glass (of a beacon) and glass (of a glass block) not a bug, and wanting glass and glass to be consistent is a feature request? All kinds of glass blocks (both normal glass blocks and all stained glass blocks) cull themself. Why should the glass of a beacon be any different?
Relates to MC-119856 as both involve block faces not being culled where they should be.
Relates to MC-135986 for the same reason.
May relate to MC-109087 for again the same reason.
May actually be blocked by/a duplicate of MC-109087, as beacon glass doesn't actually cull against anything
Feature request, not a bug, for feature requests go to the minecraftsuggestions reddit.
