Black screen on monitor connected to DisplayLink dock on machine startup

Reported by aleksand...@displaylink.com, Nov 9 
Chrome Version: Google Chrome 72.0.3593.0
Chrome OS Version: 11210.0.0 dev-channel chell
Chrome OS Platform: HP Chromebook 13 (Chell)
Network info: N/A

Issue appears also on canary channel R69 and R72

Steps To Reproduce:
(1) Connect at least one 4K monitor to Dell UNO dock via DisplayPort
(2) Connect the dock to Chromebook via USB-C, wait for the screen to appear
(3) Disconnect the docking station and the latop, but keep the docking station powered on
(4) Power off the computer
(5) Connect the dock via USB-C
(6) Power-on the computer

Expected Result:
After booting-up the system indicates the external monitor being added, monitor is operational in the system.

Actual Result:
Monitor is not seen by the OS (checked after logging in) and remains blank.

Please note the pretty distinctive series of disconnection-related messages from evdi module at the end of dmesg log.
IMPORTANT: so far not reproducible with OS verification off.
From what we have discovered so far is that the crucial elements for the reproduction are:
4K monitor
USB-C connection
Externally powered docking station.

How frequently does this problem reproduce? (Always, sometimes, hard to
reproduce?)
Often, ca. 20% of times.

What is the impact to the user, and is there a workaround? If so, what is
it?
Power-cycling the dock or replugging it usually helps, i.e. it makes the screen appear. Another option is using USB type-A, then the situation does not occur at all.

If this only happens when in normal mode (verification enabled) then it is probably a race, as the big difference (at lest with regard to displays), is timing, developer mode tends to be slower due to the dev mode screen.

If this only happens on the USB-C port and not the USB-A port that is interesting, it may indicate something with our USB-C negotiation?

I also wonder if this happens on cave or caroline (probably).
