Bug description

I use playerctl for audacious on my mediakeys as I ONLY want them to ever affect audacious.
It all works fine - until I restart: Then the play-pause functionality stops working and is only "play" (cannot toggle).
It starts working again when I just "re-apply" (changing nothing) the shortcut.

Steps to reproduce

• requires audacious and playerctl apps (in this scenario)
• remove play and pause mediakey shortcuts from sound and media default shortcuts
• assign "playerctl -p "audacious" play-pause" as a custom keyboard shortcut assigned to mediakey play/pause (I do not have separate physical keys for play and pause)
• verify it is working on audacious
• restart
• verify that the shortcut no longer can pause/play toggle - only play (restarts song)
• verify that that simply re-assigning (not changing anything) the previous shortcut will restore play-pause functionality.

Expected behavior

Expected behavior would be that this last step (re-assigning each boot) is not necessary.

Additional information

No response

Start by tracing Cinnamon's custom keyboard shortcut handling across restart and session restoration, then reproduce the issue with Audacious and playerctl -p "audacious" play-pause using the listed steps. Done means the custom media-key shortcut still toggles play and pause after restarting, without reassigning it.
