Scripting event "minecraft:player_destroyed_block" only fires on certain blocks

The event "minecraft:player_destroyed_block" only works on certain blocks. So far it's been narrowed down to blocks that you destroy with their right tool - including everything that can be broken with your hand while still giving loot.

What I expected to happen:

The event fires on every block the player has destroyed.

What actually happened:

The event fires on certain blocks that match the requirements mentioned above.

Steps to reproduce:
1. Join a world that has the following server script enabled:

const system = server.registerSystem(0, 0);

system.initialize = function() {
	this.listenForEvent("minecraft:player_destroyed_block", eventData => this.onPlayerDestroyedBlock(eventData));
}

system.onPlayerDestroyedBlock = function(eventData) {
	let data = this.createEventData("minecraft:display_chat_event");
	data.data.message = "Block destroyed";
	this.broadcastEvent("minecraft:display_chat_event", data);
}

2. Destroy a block in survival mode.
3. If you destroy the block with the right tool, a chat message should appear. If you do not destroy the block with the right tool (ex: destroy stone with your hand), a chat message will not appear.
