Cannot cast or trigger curse when using Replica Doedre's Damning Ring

I had an idea to leverage the curse mastery with 0 curse limit to always apply curse to non-cursed enemy for sustain. However, there seems to be no recovery when I use any curse on hit item. I then find out that I cannot even mannually cast curse with the Replica Doedre's Daming ring on, even though the curse icon was not greyed out, which indicates I should be able to cast it.

Could you please check if this is intended? I don't think this is the intended behavior based on the wording.

To benefit from the mastery you have to curse enemies. With 0 curse limit you can't do this.

Similarly how you can't press any totem skill with Runebinder. I agree this is not intuitive, I would expect a properly cast curse that while doing nothing itself could e.g. still proc on/when cast effects.
