Running xdg-desktop-portal sets the cpu governor to powersave if it was
previously set to performance on first run

Steps to reproduce:

-Boot up a system to login manager.

-log into icewm session.

-start xterm

set the cpu governor to "performance" by running this in xterm:

sudo cpupower frequency-set --governor performance

- run xdg-desktop-portal in xterm.

What should happen:

the cpu governor is still set to "performance".

What actually happens:

the cpu governor is now set to "powersave" for some reason.

Absolutlely zero interesting output containing "governor" or "powersave" from
journalctl...

Any idea what might be wrong here?
