When I create local player game and open it to LAN, I'd expect to see players that log in.

What happens is I don't see other players.

Affected versions:

I've tested that in worlds created in 19w02a and 19w03b.

When using 19w02a I see players normally. 

Affected players:

Both host player cannot see the joining LAN player and vice versa.

The problem exists independently of game mode: creative and survival game modes were tested.

Scope of the bug:

I can see changes to the world made by each player just fine (in particular I tested: blocks broken or placed, tamed wolves following other player, doors and levers being activated, composter being filled). Only the player is invisible. Sounds made by the player (climbing the ladder, steps etc) are heard normally.
