Unusual access: Can install Minecraft Dungeons without purchase

Hi everyone,
I want to share a bug I discovered with my account. I purchased Minecraft Legends using a digital key and activated it through the Microsoft Store. The game installed and I was able to play it normally.
But then, I noticed that I can install Minecraft Dungeons without having purchased it. I'm not sure if this is a bug, an oversight, or intentional, but it seems unusual.
Just a heads up for anyone else who might experience this. If you have any info or suggestions, please share!
Thanks!
