Shulker bullets still give you the effect (and follow you) if you go into creative mode

The bug

When you go into creative mode after a shulker as shot at you, the shulker bullet will still follow you and give you the effect despite being in creative mode. Relates to MC-94389, on Java Edition it will only follow you without giving the effect.

How to reproduce:

1. Place a command block with the command

   gamemode 1 @p

2. Place a button or pressure plate next to it
3. Spawn a shulker
4. Go into survival mode
5. When the shulker shoots at you press the button or activate the pressure plate

Observed result: The shulker bullet followed you and gave you levitation despite being in creative mode.

Expected result: The shulker bullet should not follow you in creative mode and should not give you the effect.
