How to enforce Large Text in GNOME Web?

When I enable *Large Text* in a GNOME/Wayland desktop session it works in most applications. In GNOME Web it's a bit different: * browser chrome gets bigger * some websites get bigger (e.g. https://en.wikipedia.org/wiki/Main_Page ) * some websites stay the same (e.g. https://arstechnica.com ) I get around this in Mozilla-based browsers by setting layout.css.devPixelsPerPx which embiggers everything (ref. https://superuser.com/a/1268867) In GNOME Web there's a GUI tool to zoom in which has the same effect, but the effect does not persist and does not get applied to all tabs/sites. How can I make it persistent and universal?
