[slongano]

My Home Assistant version: 2024.2.2
Core 2024.2.2
Supervisor 2024.01.1
Operating System 11.5
Frontend 20240207.1

What I am doing:
I used the trashcan button to eliminate a browser

What I expected to happen:
That the device and all associated entities are cancelled
BTW, none is used in automations or referenced anywhere.
What happened instead:
That the device and all associated entities are still there, of course they are marked as unavailable
This even after restarting HA (full restart).
Minimal steps to reproduce:
Do what I did in What I am doing:

# The least amount of code or steps possible to reproduce my error

# Put your code/steps here
No code, all from the UI

**Error messages from the browser console:**

None
