Bilateral Intersection Observer?

Question

htaccess

Hey! There is a list that needs to be rendered from the middle and loaded when scrolling in both directions.

Scrolling down works as it should, up doesn't. I can't figure out how to get around this behavior

Illustrative example

The top trigger fires only once when scrolling up, since the scroll "rests" on the top of the block

Answer 1

Write code so that there is a vector.
Profit!
