Yeah, my money is still on a pebble between the dust shield & the rotor. It could be the bearing, but you'd think the mechanic would have noticed it. It probably never occurred to him to look for a pebble.
One possible reason the noise is intermittent could be that when you go in reverse, it dislodges the pebble, and then over time it find its way back to that prefect place where the rotor rubs against it and causes the heat shield to basically harmonize and make the squealing sound.
