Attribute-swapping in creative with nondestructive weapons destroys blocks

Short description:

While practising spear-macing (relies on attribute-swapping) in my superflat world in creative, I accidentally aimed at the ground and ended up destroying a block.

So I decided to test it in a more deliberate manner.

Reproduce:

1. Load any world in Creative

2. Get a mace and spear

3. Attempt attribute-swapping aiming at any block

Expected:

Blocks do not get destroyed

Reality:

Blocks get destroyed without particles

(Done with the help of a macro that automatically swaps to the mace hotbar slot after pressing attack)
