Blocks which are mined quicker with a sword should not take 2 durability points when broken with a sword (per MC-195168 being a valid bug). However, certain blocks like leaves are in the #sword_efficient tag, whilst still being broken faster with a sword, still reduce the durability of the sword by 2.

Affected blocks

• All Leaves
• Big Dripleaf and Dripleaf stems
• Carved Pumpkins
• Chorus Flowers & Plants
• Cocoa Pods
• Glow Lichen
• Jack o Lanterns
• Melons
• Pumpkins
• Vines

Steps to reproduce

1. Look at leaves and with the debug screen observe that they are in the #sword_efficient tag
2. Break them with a sword in survival mode
3. Notice the sword takes double durability damage

Expected results
Swords would take double durability damage only when breaking inappropriate blocks like dirt

Observed results
Swords take double durability damage even when breaking blocks like leaves which are in the #sword_efficient tag and thus swords are an appropriate tool for breaking
