Glitch when riding the Oak Boat on a very narrow river near land

When you go to Minecraft or Minecraft: Education Edition, this weird glitch occurs. It starts when the boat is riding and it actually goes all the way down to the void [*I'M SERIOUS DON'T MAKE A JOKE ABOUT IT*]. This is similar to spectator mode where u can fall down and kill yourself in-game. 

Note: It only affects in creative mode ONLY.

ALSO, DO NOT THINK I WAS GOING TO KILL MYSELF IN-GAME THIS IS EXTREMELY SERIOUS.
