In the crafting table's recipe book, blocks crafted from wood usually are displayed as a single icon that changes to show all of the wood types. However, the mangrove fence and the mangrove fence gate recipes are listed as separate icons instead of being grouped with the fence and fence gate recipes of the other wood types.

- Right-click on the crafting table, and open the recipe book.
- Type "fence" into the search bar.
- Observe that there are 2 separate icons for fences and also 2 separate icons for fence gates.
There should be one icon for the recipe of each block, and it should include mangrove as one of the wood variants that the icon cycles through.
For fences and fence gates, mangrove has separate recipes from the other wood types.
