Some icons are missing when adding custom icons via GResource
Steps to reproduce
- Start a new project on GNOME Builder
- Migrate it to GTK 4
- Add a custom icon to the project
- Reference the icon on the gresource.xml file
- Add a GtkImage to the window with
icon-name=go-home-symbolic
- Export the bundle
- Install and run the app
Current behavior
The image-missing
icon is shown instead of go-home-symbolic
Expected outcome
The go-home-symbolic
icon should be shown correctly
Version information
GTK 3.99.2, installed from org.gnome.Sdk/x86_64/master
Additional information
Observation: This seems to occur only with an exported Flatpak bundle, and not when you run the app with the "play" button on GNOME Builder
