Delete device and entities for tags removed from the AP

[TheQue42]

Describe the bug
When I delete a tag in the AP, its entities seem to be left forever, and I cant even delete the entities themselves, one by one.

To Reproduce
Delete a tag from the AP, and wait until all entities become unavailable.

Expected behaviour
Preferably that the entire device would be deleted automatically, but manual deletion possibilities at least. Either in the same way that you can delete on old MQTT entity that is lying around, at worst case by least by manually deleting all entities, (if that deletes the device, but I dont actually think it does.)

I know I can manually shut down HA and start fiddling with the files in .storage/core.*, but that seems like an error workaround, and not preferable w.o.w.

Screenshots
Enable something like this, if possible?

Additional context
On a side note, is there any reason why the entities such as open_epaper_link.00001834520cdadc, that must be used in drawcustom, are not part of the device they actually refer to?

May I ask, if there is a way to delete it nevertheless? I think, the integration needs to provide an unique id to the tags and entities to enable that?
