Zealot Talent "Rising Conviction" either bugged or has wrong tooltip

The tooltip for the Zealot Talent “Rising Conviction” says:
“+4% damage for 5s on hit. Max 5 stacks”
This effect only applies to Melee hits but other effects which only apply to melee hits read “on melee hit”.
It’s unclear if this is supposed to work for both ranged and melee hits (which I think it should, Zealot has been nerfed enough) or if the tooltip for the feat is just wrong.
