I tried running some QT5 apps from CRT and noticed that they were not using their usual dark mode.
It turns out that CRT has cleared this variable. Why is that, and can it be fixed?

I found this by comparing the differences from running env in Cool Retro Term versus LXTerminal. Normally, QT_QPA_PLATFORMTHEME=qt5ct.

OS information: Raspberry Pi OS Bookworm 64-bit, CRT was installed using Pi-Apps.

It seems that the variable is cleared deliberately. f157648d1e/app/main.cpp (L36)

As an easy fix, could the variable's original value be captured, and then passed to child processes that are launched by the shell?
