gnome-control-center disappeared when dock move to bottom

[hendra]

Package : gnome-control-center
Package version : 1:3.28.2-0ubuntu0.18.04.2
Ubuntu release 18.04
Hardware : Processor sandybridge i3 2.2Ghz Memory 3GB Disk capacity 128GB

I will move the dock position down. I open the gnome-control-center and select Dock and move the position down. It turns out that the settings window display disappears as minimized. I screenshot but it automatically captured on different workspace.

I have reinstalled the package but it remains the same (window setting disappears)

I also tried it from the live session mode and the same thing happened. But if I move the dock position to the right, the settings window still looks like it usually does.

I've screen captured all of these experiments.

Thank you for your bug report. What screen resolution are you using? Could it be that there is not enough vertical space to fit the settings dialog when the dock is at the bottom?
