player able to spin 360degree in Y axis when using command during the "game menu" screen

I was trying to test the /tp command to change the my facing,but i found that I can keep spinning

What I expected to happen was...:
After entring the game menu screen,I should stay still 

What actually happened was...:
you continue to spin from your back

Steps to Reproduce:
1. go and start a new world and open to LAN
2. place a command block with "execute as @e[tag=spin1] at @s run tp @s ~ ~ ~ ~ ~1"
3. run command"/tag @s add spin1"
4.you will stay still when you face the ground,but when you pause the game/open the command block GUI,you will start to continue spinning 
P.S: this doesn't work on other entity like armor stands
