For jellium slabs, we prove analytically and numerically that in the vacuum region far away from the surface $\\varepsilon_{x}^{\\text{Slab}}(z \\to \\infty) \\to - e^{2}/2z$, {\\it independent} of the bulk electron density, which is exactly half the corresponding exact-exchange potential $V_{x}(z \\to \\infty) \\to - e^2/z$ [Phys.
