So, looks like I can reproduce this bug with 100% reliability.
When the phone is in the normal (working) state, if I receive an incoming call and I don't pick it up, the incoming notification disappears after 1 minute (I ran a stopwatch, and measured 59.66 seconds), but the phone continues ringing and vibrating.
