`~/.config/pipewire/media-session.d` created even though XDG_CONFIG_HOME is set to other location

Version, Distribution, Desktop Environment: 0.3.22, Arch Linux, i3

Description of Problem:

I'm setting XDG_CONFIG_HOME to ~/.local/config in the profile file, but PipeWire ignores it completely and instead creates .config/pipewire/media-session.d in $HOME. There is no $XDG_CONFIG_HOME/pipewire at all.

I was suspecting that service could be being launched before the variable is set, but it doesn't seem like it, as I'm already in i3 before PulseWire is started.

PS. Shouldn't media-session.d be stored in XDG_DATA_HOME?
