Affects Version/s: Minecraft 1.11.2
Fix Version/s: None
As said, when standing in a Nether portal and trying to open a chest, it stays opened, but GUI is not displayed. It is closing when opening an inventory or a chest (no matter which).
I think it is happening because you can't open any GUI while standing in a portal.
Steps to Reproduce:
1. Put a chest near the portal (no matter what type, should work on all).
2. Walk in the portal (just touch it).
3. Right click on a chest.
Tested only on 1.7.2 (I know that there is 1.11.2)
