I refiled the bug at bugzilla.gnome.org as bug 790040. The link is: https://bugzilla.gnome.org/show_bug.cgi?id=790040
I'm really surprised that there are not more complaints about this. To be fair, the dock+external monitor setup has NOT worked perfectly in any release Ubuntu release, including 16.04. Although, before 17.10, trouble only arose when moving the laptop between docks with different monitors, so it was tolerable. I sure hope this can be fixed. I suppose I could cook up some sort of udev script to handle dock changes for my situation but that is horrible kludge, not a fix.

If I open the lid while on the dock, gnome detects the external monitor and blanks the laptop display. Then, closing the lid results in suspend. As a work around, using tweak tool (or UPower) to ignore the lid, does prevent the suspend. But it is not automatic; each time, one must bring up the gnome control panel->devices->displays and manually select single display. Then the lid may be closed without suspend. This worked fine in 17.04, so I'm hoping that the provides enough clues that this can be fixed easily. Thanks! I am enjoying the new Ubuntu 17.10 generally, but this situation is annoying.
