Chrome web apps added to desktop are missing icons

[Alan Pope 🍺🐧🐱 🦄]

In Google chrome (and chromium from the archive) it's possible to add a desktop icon (like a webapp) via kebab menu -> more tools -> Add to desktop.

This adds a launcher on the desktop and to the menu. On other desktops (such as Unity) this works as expected.

On an up to date Ubuntu Artful the icon on the desktop launcher is missing. The icon in the launcher is fine however.

The desktop icons actually aren't part of gnome-shell. It's nautilus-desktop, which may also go away in future releases (!) It's also an X11-only app so depends on Xwayland (!)

Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue you are reporting is an upstream one and it would be nice if somebody having it could send the bug to the developers of the software by following the instructions at https://wiki.ubuntu.com/Bugs/Upstream/GNOME. If you have done so, please tell us the number of the upstream bug (or the link), so we can add a bugwatch that will inform us about its status. Thanks in advance.

indeed, it doesn't seem due to the .desktop files since copying one from /usr/share/applications has the same issue
