I confirm your report.

Also works the other way around with fern)

Steps to Reproduce:

1. Place fern and grass.

2. Only take the grass / fern into inventory.

3. Go to a slot without grass / fern.

4. Copy the fern / grass (if you took the fern, then copy the tava, and if you took the grass, then copy the fern).

Observed Results:

The slot with the wrong item will be selected (if you copy the grass - fern, and if the fern - grass).

Expected Results:

Items are chosen correctly.

Note:

These items with empty inventory are copied correctly.

If you have both a fern and a grass in your inventory, then when you copy the grass, the fern will be selected, and when you copy the fern, the fern will be selected...
