Switching gamemode from spectator doesn't render player hand

After switching to spectator mode via F3+N on a 20w18 a server, the player's hand disappeared along with any items the player is holding. There was no seeming way to get the hand to return through changing gamemodes of any kind. This error persisted across servers and single player worlds until the game was relaunched entirely, of which the hand model finally returned. The player model in the player ui and in F5 were not affected. 

When attempting to recreate the bug after relaunch, the error seemed to no longer be persistent or repeatable.
