"Life Regeneration Is Applied To Energy Shield Instead" does not affect Life Regeneration Rate

EDIT: Found this is identical to Zealot's Oath from PoE1, however ES Recharge rate does not apply to Regeneration rate, so there doesnt seem to be a way to scale it unlike in Poe1


While using a Soul Tether with the replaced mod "Life Regeneration Is Applied To Energy Shield Instead" any Life Regeneration Rate mods do not apply to the ES Regen. This seems odd considering it does affect "Regenerate % of Max Life" mods, converting them into "Regenerate % of Max Energy Shield"


Is this intentional? As the mod does only state "Life Regeneration" and not "Rate" but it seems odd to exclude that, as I'd consider Rate as part of the regeneration mechanic that would be converted??
