Devices are duplicated when there are multiple Bluetooth adapters

[tkashkin]

What Happened?

I have multiple bluetooth adapters connected:

• Onboard Intel AX200 Wi-Fi + Bluetooth
• Broadcom BCM20703 Bluetooth controller that's built into the HTC Vive Link Box

Bluetooth settings plug shows each discovered device multiple times if it's found by multiple adapters:

Discoverable as shows the name of the first adapter initially, but changes to the name of the last adapter when the Bluetooth plug is reopened without fully closing the System Settings app:

I can connect an old Bluetooth 2.0 USB adapter to see even more duplicated devices (not all because this adapter can't interact with BLE devices):

Steps to Reproduce

1. Connect multiple Bluetooth adapters
2. Open Bluetooth plug in System Settings

Expected Behavior

I would expect any behavior of the following:

• There's a way to select a preferred Bluetooth adapter if there are multiple and it's possible to disable the other adapters
• Devices are grouped by adapter and it's clearly visible which adapter will be used to connect to the device
• Devices with the same address are only shown once and it's possible to select an adapter to use, maybe even per-device
• Only one adapter is used and others are ignored (either the default set in bluetoothctl or the first one) - this seems to be what GNOME does
