no DISPLAY environment variable specified #62

When using flatpak-spawn I get "no DISPLAY environment variable specified" though DISPLAY is in env and is correct

[dk@sys dk]$ echo $DISPLAY
:20

it works as expected if I enter bash and then run firefox with DISPLAY set

[dk@sys dk]$ distrobox-host-exec bash
[dk@localhost dk]$ DISPLAY=:20 firefox
flatpak-spawn --host firefox
Error: no DISPLAY environment variable specified

But adding the env works

flatpak-spawn --host --env=DISPLAY=$DISPLAY firefox

Running in an archlinux container

pacman -Q flatpak-xdg-utils
flatpak-xdg-utils 1.0.5-1

It doesn't automatically pass everything through as it really doesn't make sense to. What DISPLAY equals in the sandbox doesn't even necessarily match the host.

The environment it gets spawned in is up to the environment of the systemd service org.freedesktop.portal.Flatpak.

Thanks, that makes sense
