Throwing an ender pearl into the exit portal sometimes sends you to the world spawn point

The Bug:

Ender Pearling at the Dragon portal sends you to world spawn if thrown at a certain angle even if you have a respawn bed in the overworld.(Minecraft Realms)

Steps to Reproduce:

    - Place a respawn bed outside the portal leading to the stronghold portal and sleep in it to set your respawn point.
    -Walk to the Dragon Portal and throw the pearl at a certain angle(I am assuming at an angle so that the pearl doesn't collide with anything in the portal evident from the lack of damage I am taking after pearling)

    -If you throw it an an angle where your pearl collides with nothing before it enters the Dragon portal it will teleport you to the world/seed spawn.(evident from the lack of damage I take in the first clip - No I did not swap or destroy the respawn bed)
    -It will teleport you to your bed if it collides with something before or after the toss (damage taken due to the pearl landing on a collision object)

Observed Behavior:
When it doesn't collide with the insides/outsides of the portal(pillar or the borders) it TPs you to world spawn( I am assuming the lack of collision detection leads to this behavior)

Expected Behavior:

It is supposed to teleport you to the bed outside the portal where you have initialized your respawn point.
