On Android, the four 80x80 page-navigation buttons stay mounted on top of the foliate viewer even when hidden (opacity-0). pointer-events:none can't be used on Android (it breaks touch propagation to the iframe), so the prev/next-section buttons already have an h-4 w-4 fallback for the hidden state. The prev-page / next-page buttons were missing this fallback and therefore kept covering ~80x80 hot zones in the lower-left and lower-right of the page, swallowing long-press touches on the first/last words of the bottom two lines so they could neither be highlighted nor open the toolbar. Apply the same h-4 w-4 fallback to those two buttons.
