boot disconnected, connect, disconnect

Using kernel 4.9.0-0.rc1.git0.2.fc26.x86_64 on a docked haswell laptop, I'm
seeing that the DVI connector on the dock is always reported as connected after
disconnecting it. I'm attaching two dmesg drm.debug=0x3f logs, on the first I
boot disconnected and then connect and disconnect, while on the second I boot
up connected and then disconnect. On both the end result is

$ cat /sys/class/drm/card0/card0-DP-4/status 
connected
