Hotplug: Turning off DisplayPort monitor also tears down its associated desktop.

If Xorg is able to detect that the monitor got turned off, chances are
that it will notify the running apps via xrandr and the desktop
environment will adjust things accordingly, this is all perfectly
normal and expected.
For example, if windows are left on an output which is gone, it means
they won't be accessible to the user which is a problem, so xfwm4 will
move them so at least a small portion of the window remains visible on
whatever monitor is still present.
Again, this is the desired behaviour and not something that was
changed in xfce-4.12 (previous versions did exactly the same)
So, to me, what you describe looks like a well written desktop :)
Cheers,
Olivier
