Placing blocks triggers item_used_on_block, affecting "Not Quite 'Nine' Lives" advancement

The bug

The item_used_on_block trigger also works when placing blocks. This causes the "Not Quite 'Nine' Lives" vanilla advancement to be granted when placing glowstone on the respawn anchor instead of charging the respawn anchor.

This could be intended, but then there should at least be a condition to check whether this was a block placement or a block altering.

How to reproduce

Using the vanilla advancement
  1. Set a respawn anchor with charges state set to 4

    /setblock ~ ~ ~ respawn_anchor[charges=4]
  2. Shift right click on it with glowstone
    ❌ The "Not Quite 'Nine' Lives" advancement is granted

Using a generic advancement
  1. Create an advancement with the item_used_on_block trigger and a function

    {
      "criteria": {
        "place": {
          "trigger": "minecraft:item_used_on_block",
        }
      },
      "rewards": {
        "function": "test:use_item"
      }
    }
  2. Create a function that prints a message every time this advancement is granted

    advancement revoke @s only test:use_item
    say used item!

    ❌ The advancement triggers every time you place a block

Confirmed in 1.16 Pre-release 2.

Confirmed for 20w30a. This overlap of functionality is annoying. I can't detect a player removing a music disc from a jukebox without also detecting when a player places a block against an empty jukebox.

Confirmed for 1.16.2 pre-1. I don't know if this is a separate issue, but placing the block itself will trigger the item_used_on_block criteria if the item is not defined and if you are replacing a non-air block by placing it (like grass or fern).

Can confirm in 20w49a.
