But then it's really a problem of the icon theme I think.
Yeah, so we need to get an idea that major distros provide something sane for `-symbolic`.
On this Mint (not the latest but still supported) `find /usr/share/icons -name "edit-clear-symbolic*" -print ` only finds anything in Adwaita. But `find /usr/share/icons -name "edit-clear*" -print` finds lots.
