I experienced this on a singleplayer world on both ends; I somehow escaped suffocating to death in the Nether despite not knowing what was happening. I died in the overworld but my stuff was close to an old base so nothing frustrating happened, but it was a big scare and I could of easily lost my progress had my coords been any different. Safe to say that going trough portals is not recommend until it's fixed, which really sucks because it locks out a lot of items.
