Having exact same issue. 1.14.2 java edition on Mac. I've gone more than 800 blocks away from zombie pigmen in the nether, waited for more than 10 minutes then returned and they are still going agro. I have not attacked them back and they have now followed me through my portal and I'm stuck in my house surrounded by a huge hoard of them. Tried pillaring up through my roof for more than 100 blocks and waited another 10 minutes and it changed nothing. Gah!
