Particles are created when punching nether portal blocks

Confirmed. If this is intentional, the end portal and end gateway not emitting particles at all might be a bug (but I recall that the current alternative to that is missing texture particles, so that might be intentional as well).

Can confirm in 1.17.1.

Can confirm this in 1.18 Pre-release 1. Here are some extra details regarding this problem.

The Bug:

Nether portal blocks produce particles when being hit.

Other portal-like blocks such as end gateways and end portals don't produce particles when being hit, therefore introducing an inconsistency with nether portal blocks.

Steps to Reproduce:

• Switch into creative mode and obtain a sword.

• Summon a nether portal block nearby.

/setblock ~ ~ ~3 minecraft:nether_portal

• Whilst holding the sword in your hand, begin hitting the nether portal block.

• As you do this, take note as to whether or not nether portal blocks produce particles when being hit.

Observed Behavior:

Nether portal blocks produce particles when being hit.

Expected Behavior:

Nether portal blocks would not produce particles when being hit.
