Current Behavior

In XFCE, using i3lock --pass-media-keys does not pass the media keys to the desktop environment. This happens regardless if the XF86 keys are bound in xfce4-settings, or through an external application such as volumeicon. I'm unsure why this happens, as --pass-media-keys works as expected in i3.

Expected Behavior

--pass-media-keys should pass the media keys to the underlying environment, regardless of the used window manager.

Reproduction Instructions

Install XFCE (pacman -S xfce4), bind XF86AudioMute either in keyboard settings or a program like volumeicon, try to mute when the screen is locked with i3lock --pass-media-keys.

Environment

Output of i3lock --version:
