Although Glass Bottles can be funneled into Brewing Stands via Hoppers in both Java and Bedrock, on Java it can only put one in each slot, whereas on Bedrock, it can put up to 64 in each slot.

How to reproduce:

1. Connect a Hopper to the side of a Brewing Stand

2. Place 4 or more Glass Bottles in the Hopper

Expected Result:

Three of the Glass Bottles get funneled into the Brewing Stand, and the rest remain in the Hopper

Observed Result:

The Hopper is able to put multiple Glass Bottles in the same slot.
