When being teleported into the air, a server with flying disabled will kick you for flying in survival/adventure mode.

Steps to reproduce:

1. Create a server with allow-flight=false
2. Enter the server
3. Use

   /gamemode survival
   /setblock ~ ~-1 ~ chain_command_block{auto:1b,Command:"teleport @p ~ ~3 ~"}
   /setblock ~ ~ ~ repeating_command_block[facing=down]{auto:1b,Command:"teleport @p ~ 0 ~"}

4. Wait for a few seconds
   -> Get kicked for flying

Expected behavior:
Since it's a command the server (via functions or command blocks) is running, the "fly timer" should be reset.
