+        #
+        # 1. `interact` - on line `result = await interact(` - calls `workflow.close_others` and `_button_request`
+        # 2. `workflow.close_others` may result in clearing of `context.CURRENT_CONTEXT`
+        # 3. `_button_request` uses `context.maybe_call` - sending of button request is ommited
+        #    when `context.CURRENT_CONTEXT` is `None`
+        # 4. test gets stuck on the pairing dialog screen
+        #
+        # The hotfix performs `workflow.close_others()` and in case of clearing of `context.CURRENT_CONTEXT`, it
+        # is set to a functional value (`self`)
