This happens to me as well, whether it's going into the overworld or the nether. Sometimes like in your video, I don't fall and respawn at the portal, I'll just fall.
Or, I'll fall, respawn, and fall again.
Another issue I've had with the portals is "suffocating in a wall" while attempting to go through.
I had to use my recovery compass to find my stuff, and it was in some random spot where there isn't a portal.
