On BDS-2346 it was stated to comment or create a new ticket. It's been nearly two weeks since I commented so I decided to open a new ticket.
The original ticket reported that portals were duplicating in Survival, which multiple users believed was a result of a portal perhaps not being lit. However, this glitch is also occurring in Creative.
Original Comment
Hey, this glitch is still occurring on Bedrock Multiplayer (v1.21.30). Not only survival but creative. This recently happened to a friend, however, the glitch only consistently occurred to players who weren't the owners of the world. The issue is very much unresolved.
Steps to Recreate The Problem:
Create a world on Bedrock v1.21.30.
Have a player join your world.
Create a Nether Portal and have them go through.
Have them return to the Overworld.
A second nether portal should appear within the chunk. If not, repeat with a different player.
Up to three portals can appear in this way. After three, destroying them will allow three more to appear.
Additional notes:
The owner of the world can sometimes trigger this glitch, but not always. As of now, I have not seen any connection that causes the owner of the world to trigger this glitch.
There are no mods enabled in the following video. Only one player is using ray tracing (the owner).
In the following video, no experimental features are enabled.
Video is attached below.

So far I've only seen it occur in Bedrock, and it's only been reported to occur in Bedrock. After quickly testing Java singleplayer, I am unable to replicate it.
I will attempt to test Java multiplayer at the earliest convenience.
I was asking if it happened outside of BDS: https://www.minecraft.net/en-us/download/server/bedrock
I will take your answer as a yes and move it to the correct project

What's described in the linked (MCPE-39609) issue is similar, but the offset does not appear to be the same.
The attached videos show only one nether portal being created. It does not show two in the same chunk.
It looks like there is a portal among the trees in the background, but that is much farther away than one chunk. If that is the portal that the player went through, then the portal it sends to on the nether side may not be close enough to return to it. Does that explain your issue? (It is described at MCPE-39609)
