Some applications don't detect the file chooser

I am not sure if this is related to non-QT applications. Upon investigation, I noticed that xdg-desktop-portal does not identify XDG_CURRENT_DESKTOP=LXQt, and some applications, such as ruffle, cannot identify the portal frontend. Setting XDG_CURRENT_DESKTOP=LXQt before launching DBus in /usr/bin/startlxqt solves the problem.

See #605 and especially its review by @palinek.

That probably wouldn't work in non-systemd environments, which is my case

And that's a good reason to keep your report open: you may have found a better solution under Wayland too (see lxqt/lxqt-wayland-session#90).

Setting XDG_CURRENT_DESKTOP=LXQt before launching DBus in /usr/bin/startlxqt solves the problem.

I'll test that later, on Wayland it doesn't make a difference, without systemctl --user import-environment XDG_CURRENT_DESKTOP in niri the portal isn't loaded.
But the order could still be changed IMO, I can't see a reason why this could be bad.
