"scoreboard players display" settings sometimes reset on world load

Expected result:

When you use scoreboard players display on a player name, what you changed should be saved and still be there when you rejoin the world.

Actual result:

Sometimes (not always), the applied change gets reset on world load.

How to reproduce:

• Create a scoreboard objective: /scoreboard objectives add Test dummy

• Display it on the sidebar: /scoreboard objectives setdisplay sidebar Test

• Set a player’s score so it shows up: /scoreboard players set @s Test 5

• Change a display setting: /scoreboard players display numberformat @s Test blank

• Rejoin the world
