Thanks to a little off list help from Jacque, I was able to get this working. Here's the key piece:
wait 10 milliseconds -- Panos workaround, bug #18924 mobileControlSet pName, "hScroll", the hScroll of control pName mobileControlSet pName, "vScroll", the vScroll of control pName The workaround in the bug report actually says wait 0 ms, but I found that I had to increase it a bit for it to work on my test Pixel (I didn't try to see how low I could go though). I'm replying to myself to put the information out there in case someone is searching the archives.
