I am having this issue on a bedrock server. It was updated to 1.13 from 1.12.
This issue is confirmed to be affecting multiple users.
The teleports drop us into the nether thousands of blocks from the portal with no nether portal to return to the overworld.
The random teleport happened 100% of the time when going through each nether portal after the update. After the first entry of each portal, the occurrence rate started sharply declining, until now where it hasn't happened to me at all today.
When it happens, the world transitions to a generating world loading screen. It remains stuck on this screen for an extended time. I suspect it is waiting to generate all the chunks in viewing distance. I upped the viewing distance cap to 80 chunks, and it takes an extended time to load all the chunks for a new player connecting to the server as well. It has clearly loaded me into the nether despite the loading screen. I could hear enemy mobs and was actively under attack from a ghast while the loading screen was still up. In one case, I died while the loading screen was up, and when the screen disappeared, I had to respawn at my bed. If I kill Minecraft and reconnect as soon as I can see that I am stuck in the loading screen, the nether loads right away, and I can watch the chunks generating.
I am not sure why the occurrence rate has declined, even to the extent that it hasn't happened to me again today, despite attempting to repeat it. I do suspect that it is because the world has generated the full 80 chunks viewing range around the nether portal in the nether now.
*Edit* After nearly a full day of no random teleports, it has started happening frequently again.
