If one holds shift as they go through a nether portal it is as if the command is locked on the other side. Although the player will not be sneaking, he or she will not be able to open chests or use other containers, instead he or she will place a block on it just as if shift were being held down. Going back through the portal will not solve this, one must exit and reenter the world.

I just had this on 1.14.1. I went through a nether portal from the nether to the overworld and when I came through I couldn't use a any chests. Right clicking with a flint and steel lit the ground in-front of the chest and right clicking with a sign placed the sign on the chest. Shifting and unshifting fixed this issue. It seems to be 100% reproducible in my 3 tests. Here's a video of it occurring: https://youtu.be/mDDlBmYG_zk
I'm playing on 1.14.1 on a vanilla SMP server.
@unknown, your issue is probably MC-117914
I can confirm this bug. Pressing the sneak key fixes it. It seems whatever variable the game uses to determining sneaking or sneaking interaction is not reset when using portals, as you don't stop sneaking the normal method which would reset the value. Therefore, you must press sneak to start and stop, resetting the value.
