'Show the overview' keybinding should not have default value
Look at this "Show the overview" keybinding, Super+S:
That's dumb because Super alone is enough to show the overview. I was going to report a gsettings-desktop-schemas bug to remove this, but turns out that already happened three years ago in gsettings-desktop-schemas@1a5e5a54.
Looks like the keyboard panel is displaying old settings keys.
