When changing the shadow_radius of a display entity, all nearby entities update it on a client, even though the NBT says they still have shadow_radius of 0.

This seems to affect display entities of the same type, as example - if you spawn two text_display and change the shadow_radius of one of them, the other will change too, while the other display entities remain.

In the provided video, I spawn three item_display and change the radius of the middle one, the other two change it as well.

The scoreboard shows the NBT shadow_radius of the entities.

I also provide the test datapack, use function test:test to test.
