Public bug reported:

on a dell xps 15 2-in-1 (model 9575), I've enabled iio-sensor-proxy
functionality by doing:

modprobe intel-ish-ipc
echo "8086 a135" > /sys/bus/pci/drivers/intel_ish_ipc/new_id


This makes `monitor-sensor` display rotation events, and gnome-shell 
auto-rotate the screen upon receiving them.  However, immediately after 
rotating, the screen rotates back to its normal orientation (unless I quickly 
lock rotation), displaying the following in journalctl:
