Is it true that the total vapor pressure of immiscible liquids equals the sum of their individual vapor pressures?

The claim that the total vapor pressure of immiscible liquids equals the sum of their individual vapor pressures is a standard thermodynamic principle (Dalton's Law of partial pressures applied to ideal immiscible mixtures) and requires no citation.
