Hmm, this very topic came up in conversation on my group ride just a couple hours ago, as we were going south on Foothill. My friend said that if the white limit line does not extend to the bike lane (as is the case on Foothill with that T-intersection), then you don't need to stop. Sounds plausible. I'll look around the vehicle code later and see if I can find anything supporting that.
To the poster with that picture of the intersection, the crosswalks go all the way across the intersection, so I think you would be cited for not stopping, or for that matter, not stopping behind the line of the crosswalk, which is the limit line in that situation. I once got a ticket, in my
car, when I stopped past the limit line.
