Mapping physical screens to KDE containments

Hi folks,

Using a multi-monitor setup under Plasma 5 (Fedora 23), I have a
problem where the configured panel applet will disappear and not come
back if an external monitor is reconfigured to clone the laptop
monitor, and then switched back to being an independent screen.

In trying to debug that, the relevant config files seem to be
.config/plasma-org.kde.plasma.desktop-appletsrc and
.config/plasmashellrc, but those are defined in terms of containments
rather than screens, and I haven't been able to figure out where the
mapping from screen -> containment can be found.

Any pointers on how I can look up that mapping? (I was going to use
the Python bindings, but then found those haven't landed for Plasma 5
as yet)


P.S. Tips on the original "switching to clone mode and back again
breaks the external monitor's panel settings" also welcome, but not my
main focus at the moment
