alt Hacker NewsA Waymo was recently stuck on some light rail tracks in Phoenix this year [1]. Portland has a rather diverse bunch of streetcars and trams concentrated in its downtown core. Hopefully they don't get stuck on the tracks or block the trams.

From the article it doesn't sound like it was physically stuck as much as it's maps might not have been updated with the latest addition of that light rail and/or it was confused by the ongoing construction.
Definitely a big concern, but given the number of times in my lifespan that I've seen pictures or video of human-driven vehicles that have got stuck on railroad crossings (or just straight up drunk people trying to drive linearly down a railroad track)...
I would be curious to compare stats of 100,000 hours of human drivers getting stuck on grade crossings or doing something dumb, such as trying to drive around crossing barrier arms, vs 100,000 hours of automated driving. I would bet the automated driver does a lot better.
I recently saw a video from (I think not Phoenix) of 3 waymos that were next to each other blocking traffic in an intersection, refusing to move, because they were facing a traffic signal intersection where the signals had reverted to blinking red mode. Humans who paid attention when learning to drive will understand this means the intersection has reverted to a 4-way-stop due to the traffic signal failure.
The problem is that multiple red lights were blinking in view of the waymos not in sequence with each other, so the waymos interpreted it as a alternating-blinking red railroad signal crossing, and all of them refused to proceed, even when it was their "turn" in a 4-way-stop arrangement.
Well, that's the hope, but the bar is pretty low. Portlanders constantly block streetcars, usually by doing a shite job of parallel parking.
