The bug

The tag #minecraft:sword_efficient is intended for controlling blocks which can be mined faster with a sword than not, but that in both cases take a nonzero amount of time to break. For some reason, mushrooms and fungi are part of this block tag, despite it being meaningless in this sense, as mushrooms and fungi take no time to break under any circumstances.

Having these blocks in this tag is confusing for data pack creators, and also contributes to visual bloat on the debug screen.

How to reproduce

1. Look at minecraft:red_mushroom, minecraft:brown_mushroom, minecraft:crimson_fungus or minecraft:warped_fungus
2. Press F3
3. Observe the block tags

Expected results

None of these blocks would belong to the tag #minecraft:sword_efficient.

Actual results

All four of them do.

How to fix

Remove these blocks from this tag.
