Advancement trigger item_used_on_block no longer triggers when using the right click action of a block without an item

In 1.20.4 (and earlier), it was possible, to do right click detection of any block that has a right click action like so:

{
    "criteria": {
        "click_button": {
            "trigger": "minecraft:item_used_on_block",
            "conditions": {
                "location": [
                    {
                        "condition": "minecraft:location_check",
                        "predicate": {
                            "block": {
                                "tag": "minecraft:buttons"
                            }
                        }
                    }
                ]
            }
        }    
    },
    "rewards": {
        "function": "test"
    }
}

However, this no longer works in the current snapshot (note that you have to replace tag with blocks and prefix the block tag with a #)

It looks like, the advancement now requires an item to be used.

Steps to reproduce:

1. Download the 1.20.5 datapack from the attachment

2. Use a dye or glow ink on a sign
   -> ✔ You will see a chat message "Do not temper with the signs on my yard!"

3. Right click any button
   -> ❌ The advancement `buttons` does not trigger

4. Download the 1.20.4 version of the datapack (the only difference is the blocks field being changed to tag and the # being removed, because of format changes)

5. Repeat the steps above in 1.20.4
   -> ✔ Pressing a button now prints "WHY ARE YOU PLAYING WITH MY BUTTONS?!"

Expected Behavior

minecraft:item_used_on_block should work for any right click action on any block that has a right click action.

Observed Behavior

minecraft:item_used_on_block only triggers when using an item on a block.
