"""
Integration test simulating the bug scenario:
1. User disables notifications via /notifications off in WebEX
2. User creates a background task from WebUI
3. Verify that notification is NOT sent to WebEX/Telegram

This test verifies the fix for the critical bug where background task
notifications were bypassing the user's notification_preference setting.
