Although recent studies have pointed out the positive correlation between high ionizing photon escape fractions and high [O III] $88~\\mu\\mathrm{m}$-to-[C II] $158~\\mu\\mathrm{m}$ ratios found in UV-luminous star-forming galaxies at $z > 6$ with ALMA, previous studies have paid little attention to the neutral gas porosity that allows ionizing photons to escape.
