When breaking the muddy mangrove roots, the axe is the fastest tool to mine it instead of the shovel. This is different in Java, where the shovel is the fastest tool to mine the roots.
How to Reproduce
1. Place down a few muddy mangrove roots.
2. Break it with an axe, and then break it with the shovel to compare.
Observed Result
The axe is the fastest tool to mine muddy mangrove roots.
Expected Result
The shovel is the fastest tool to mine muddy mangrove roots.
As of 1.19.0.30/31, there are no default tools to break the muddy mangrove roots faster, meaning any tool would have the same breaking speed.
