Inevitable Agony + Cursed Ground does not work

In a setup with Impending Doom the Cursed Ground mechanic on any curse works because:

Impending Doom support says:

Trigger Doom Blast when curses from supported skill expire

However the same logic does not work/apply on Inevitable Agony which says:

Cursed targets take 50% of hit damage dealt to them while cursed again when curse expires.

So Cursed Ground should interact exactly the same as on any other curse here. Cursing them again with this support expires the curse and triggers the doom blast or in this case should trigger the effect of inevitable agony.
