Yeah, my reading was that the bike ran the stop sign and then attempted to make a left turn in front of the Waymo as it was going straight through the intersection.
The comment that claims bikes can treat stop signs as yield signs in California is incorrect. From the CA DMV website [0]:
> Bicyclists must obey STOP signs and red signal lights, and follow basic right-of-way rules.
There was an attempt to change this a few years ago, but it didn't pass.

Even if it had passed, it wouldn't have changed anything about this situation. Because there was other traffic in the intersection, the bicyclist would have had to yield and stop before entering the intersection.
