Inconsistent tray re-open GUI behavior

[GetPsyched]

There's no way to do this on Linux (COSMIC DE -- likely possible in KDE Plasma), but even on windows clicking the little icon doesn't seem to work (cc @jdestgermain)

To clarify, IF you click the X on nexus while logging, it remains in the tray and clicking it doesn't restore it.

If you just click on nexus in the tray (to minimize it) then click it again, it works fine.
