Title

Nether portal teleports the player after leaving the portal when switching to Spectator Mode

Steps to Reproduce

1. Create a Nether portal.

2. Enter the Nether portal in Survival or Adventure Mode.

3. While the Nether portal effect is active, switch to Spectator Mode.

4. Move away from the Nether portal.

5. Wait for the portal effect to finish.

Actual Result

The player is still teleported to the Nether even after switching to Spectator Mode and moving away from the Nether portal.

Expected Result

Switching to Spectator Mode and leaving the Nether portal should cancel the pending teleportation. The player should remain in the Overworld.
