Curiously I cannot find "GNOME Web" when searching flathub from my cosmic VM. However I installed org.gnome.Eolie from GNOME Software and observed that it is started with Adwaita and an English locale, whereas the system theme is Ambiance and locale is French.
When installing from the CLI ("flatpak install flathub org.gnome.Eolie"), the theme is Ambiance as expected. The language remains English, maybe a separate issue?
