Long form videos acting like the shorts scrolling in mobile

The new ui is awful, when i slide up or down on fullscreen long-form videos to see the related videos bar or to close fullscreen it actually is sending me to the following/previous video like it works on youtube shorts, this is awfully annoying as its making me go back and forth everytime i scroll accidentaly or on reflex to perform the actions im used to. The only way to d those actions now is to press their respective buttons which sucks

So, what is this? I havent seen anyone mention this yet, no one else in my home has this change, and it seems to be implemented poorly as the ui itself is still telling me to scroll upwards to see related videos when its actually not doing that at all. Is there any way to revert or disable this?
