Died standing in nether portal, cannot respawn

Put the summary of the bug you're having here

What I expected to happen was...:
I was killed in the nether while still standing in nether portal, and expected to be able to respawn after I died.

What actually happened was...:
I clicked the respawn button repeatedly, but the game is stuck at the death screen. When I tried to return to title screen, the game freezes and becomes nonresponsive, and crashes.

Steps to Reproduce:
1. Enter Nether through overworld
2. Die while standing in portal
3. Attempt to respawn
