meanwhile the portal hitbox in bedrock is still full block, just revert this pointless harmfull fix, it benefits no one and only takes away from the game as it renders nether portals next to useless
this issue is only apparent now because snapshot 25w04a needlessly changed portals to no longer detect full block around the portal and instead only detect when item touches the portal itself, thus breaking a metric ton of contraptions going back over a decade
not a bug, just how transparent blocks behave, dust can power upwards, not downwards, so please mojang remove this report, its intended behaviour and has been for 15 years
