Restoring the ability to place cushions at various heights inside cauldrons

This feature was removed in the 4th snapshot of 26.3. I much preferred the solution where a cushion could be placed in a cauldron at any height. It allowed for the creation of striking cauldrons where the cushion resembled a colored liquid, as well as interesting mechanisms—for instance, quickly swapping the cauldron for a redstone lamp could yield a black cushion that revealed its true color only when the lamp was powered by redstone. This enabled cool, multi-colored displays. I believe this mechanic should be brought back to the game, as it opens the door to many interesting building projects. It would be a shame for the developers to waste such potential.
