How to reproduce

Orca-slicer stubbornly uses GTK file picker on KDE.

Install orca-slicer, tried both the provided flatpak and Aur package.
From commandline, run GTK_USE_PORTAL=1 orca-slicer
Select File -> Open Project

Actual results

Actual: GTK file picker shows up

Expected results

Expected: KDE file picker shows up

Project file & Debug log uploads

No project needed

Anything else?

More notes:
GtkFileChooserNative is supposed to automatically select the file chooser based on active xdg-desktop-portal when GTK_USE_PORTAL=1.
