So, I have just tested this on the latest Fedora Rawhide and experienced the same issue as on Ubuntu 18.04 so it looks like that this is really an upstream issue.

They are installed if you run "flatpak update" from Terminal after the installation. This issue should be already fixed in GNOME Software upstream so I believe that this is a downstream Ubuntu issue. Please, fix this. Steps to Reproduce: 1. Use the latest, fully updated Ubuntu 18.04 image. 2. Install "flatpak" and "gnome-software-plugin-flatpak" packages. 3. Restart the system. 4. Download and add the Flathub repo file: https://dl.flathub.org/repo/flathub.flatpakrepo 5. Search and install the "GNOME Web" Flatpak package using GNOME Software. 6. Run the installed "Web" application. Actual results: GNOME Web is started with the default (Adwaita) theme (and without the correct locale if you use non-English system). Expected results: GNOME Web is started with the correct (Ubuntu) theme (and with the correct locale if you use non-English system).
