portal bug in minecraft beta 1.21.04

Model: Mac Sonoma 14.6.1

Issue: whenever a player goes through a nether portal, the player is stuck in the loading screen for a few seconds more than the actual time it takes for the other side to load. This issue is also in bedrock edition and can result in players dying on the other side of the portal before they even exit the loading screen. 

The bug can be replicated by creating linked portals, then putting damage sources on one portal, such as lava or hostile mobs. Then switch to survival and go through the portal, and if you have the volume up you can hear the player dying but can de nothing about it as you are still stuck in the loading screen.

Side note: I do not know if this happens for end portals as well, the loading screen duration is too short for me to be sure.
