Whenever you try to craft something out of mangrove that has separate wood types, like fences and doors, it works fine. But if something includes wood planks in its crafting recipe but doesn't have separate wood types, like chests and beds, crafting it using mangrove planks won't work. The item will disappear from your inventory less than a second after you grab it from the result slot, and you'll be given back the crafting ingredients. This happens on realms only, in normal worlds MCPE-164755 occurs.

Steps to reproduce:

1. get at least 8 mangrove planks
2. make a chest
3. try to grab the chest out of the result slot

Observed results:
The chest will disappear in under a second and you'll be given back the eight planks

Expected result:
You successfully get a chest.

Happens with beds and sticks also.
