Can confirm in 1.20.6, the bug only occurs in specific seeds and at specific coordinates. The seed I used was -7758649986327837072 and portal coords were 12550699, 71, 12550422 (the bottom left block of a typical 4x5 portal).
Note: you don't have to make the portal at exactly the above coords, or even in the same chunk. All portals within a ~50❓ block radius experience this bug
