Bluetooth Example does memory manipulation in IRQ

[32BT]

The Bluetooth example picow_ble_temp_sensor.py is not working for me. I never receive notifications of updated temperature. It seems the code attempts to add data to a set during an interrupt. This likely results in memory manipulation which is not allowed. The handle is subsequently not stored when I try the example so I never receive Notifications. If I assign the handle to a local var, it works as intended.
