[MC-173571] Regression with collision boxes of moved blocks sometimes prevent items/entities to fall through

Comparing to 1.13 (last time I used this solution) items now not always fall through the following setup. Previously, since gaps between end rods are much larger than item size, they were falling through - now they are getting stuck on end rods. Items also sometimes fall through visually, but revert back due to server side positioning

Cannot reproduce in 1.17.1.

Tested it in 24w39a and still remains an issue as seen in the attached video.

The red concrete powder visually falls through, however, returns back atop the end rod. Some stacks fall whilst the others remain on top. Also works with horizontal end rods.
