No value is stored in the player NBT to indicate which hand is set as their main hand in settings.

Expected behaviour

It is expected that since players inherit most of the applicable NBT tags stored by mobs, the LeftHanded tag would also be included.

Actual behaviour

There is no LeftHanded tag stored in the player's NBT.

Steps to reproduce

• Use the following command on a skeleton:

  /data get entity @e[type=skeleton,limit=1] LeftHanded

• Use the same command for the player

  /data get entity @p LeftHanded

• Observe that there is no LeftHanded tag for the player but there is for mobs.
