I WAS MISTAKEN

I’ve just found out this is not a bug but is intentional. You may ignore the rest of this post.

Steps to reproduce❌

1. Create a new item in a behaviour pack with the component “minecraft:digger”.
2. Add “destroy_speeds” with whatever blocks you choose. (Inside of minecraft:digger)
3. Add an “on_dig” event inside of minecraft:digger.
4. Load a Minecraft world using the behaviour pack with the item you just made.
5. Try digging one of the blocks you specified inside of “destroy_speeds”, and you will see it will only trigger the event on any blocks you didn’t specify.

Observed Results:❌

The event only happens when the player mines any block BUT the specified blocks inside of “destroy_speeds”.

Expected Results:❌

The event should occur when the player mines any specified blocks inside of “destroy_speeds”.
 

In the screenshot I highlighted the code I am talking about. I really hope this can get fixed, or at least looked into. Thank you!
