On a two person realm, when one person goes to the nether, the top half of doors near the portal (in the nether) appear in the overworld. (see image)
In my nether, there is a small room built around the portal. If two people are in the game, when one person goes through the portal, floating top halves of doors will appear in the overworld. This is frequent, but I haven't paid attention enough to tell if it always happens.
These doors seem to be "connected" to the ones in the nether. I pillared up to one of the floating doors and mined it. The similar top-half of the door disappeared for the other person in the nether. Opening and closing the door in the nether made the visual glitch revert to normal and the door didn't reappear in the over world.

Added some new screenshots. When the other player is in the nether, they can open and close the doors and sometimes (but not every time) the doors change in the overworld.

Confirmed to affect LAN as well.
To reproduce,
have 1 player in the nether, another in the over world(may affect the end as well)
Have both teleport to the same coordinates in both dimensions
Have the player in the nether place a block, nothing happens in the overworld as expected.
Hvae the player in the nether place a door, works fine.
Now have the nether player open and close the door
Which ever part of the door clicked now appears in the over world
Have over world player try to mine the door half
Bottom part of the door disappears in both nether and over world.
Place a torch on the block below the door
Torch shows up in overworld
Tap the block with a door in a place where a door can't go and the block will appear in the over world.
Will move to MCPE project as it is not just Realms
