4. Disconnect monitors.
5. Reconnect
6. Bar will be on main display but not on externals.

Fun, I've just tested this and I can see what's happening. I believe it's related to swaywm/sway#8164 (and the related gtk issue). Effectively, I have to hope that GDK and Wayland report monitors in the same order, which appears to be true until you (dis)connect one.

I'm not sure what I can do about that yet but I'll have a think.

So a fix has now been implemented in GTK for the issue. Once there's a new GTK3 release, I'll revert the logic in Ironbar to its previous implementation that should resolve this.
