A scoreboard objective with display mode below_name renders right behind the player's name

Setting a scoreboard objective's display mode to below_name makes its text render behind the player's name rather than under it.

How to reproduce:

1. Start a multiplayer server or a LAN world and join it with two accounts or have another player join with you.
2. Execute the following command:

   /scoreboard objectives add 123 dummy

3. Execute the following command:

   /scoreboard objectives setdisplay below_name 123

4. Look at the other player's name.

Expected result:

The player's name would render above the objective's text.

Observed result:

The player's name renders right in front of the objective's text.
