Subject: [PATCH] status: Pass scroll events to volume and brightness sliders

Sliders can be operated by mouse scroll, but the mouse has to be over
the slider control.  Make the brightness and volume system menu entries
forward scroll events to the sliders they contain so that scrolling
anywhere on the menu item operates the slider.

Closes https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/2795
