Vines lost when shearing many at once in a single block space

The Bug

See the screenshot for an example. It took four vines to place – one for each block face. When using shears, only one vine is returned. You can lose vines by simply filling a block space with them, then using shears and repeating.

Expected behavior: one vine dropped per side covered
Actual behavior: exactly one vine dropped

How to reproduce

  1. Place two blocks down, one block apart from each other

  2. Place a block behind the gap and above it, see screenshot

  3. Inside the hole, place a vine on each exposed side

  4. In survival mode, attack the vines using shears
    ❌ notice that the vines block drops only one vine, despite having 4 within its block space

Placement feature doesn't mean you suddenly get more out of them 🙂

I think you misunderstood this ticket. This is not a request for the ability to dupe vines by placing and breaking, this is indisputably a bug. You can lose tons of vines by simply placing and shearing. Also, is inconsistent that if there are multiple vines sharing blockspace and you shear them you only get one vine back regardless of how many vines you actually sheared at once.

Yeah I see that it is not Work As Intended anymore, but I wanted to make it clear what exactly was the bug, because if a Mojang employee didn't understand it, other people might not either.

Can confirm in 1.19.
