commit b9a4705f80e89fff3b65288cbbe8df73a365aee3
Author: Maxim Cournoyer <maxim.cournoyer@gmail.com>
AuthorDate: Sun Feb 6 23:26:24 2022 -0500

    gnu: webkitgtk: Adjust BubbleWrap wrapper.
    
    This revisits <https://issues.guix.gnu.org/40837> with a fix that doesn't
    require to have PULSE_CLIENTCONFIG point to an absolute store location, 
which
    will allow us to revert to have PULSE_CLIENTCONFIG point to a fixed location
    under /etc.  This would alleviate the need to reboot to have changes to the
    PulseAudio configuration effected.
