When a built in SVG is used as a layer symbol, the path is stored in the .qgs file as a path relative to the QGIS install directory, regardless of whether the project is configured to use absolute paths or relative paths. This is good, as it means the project file is portable between instances of QGIS installed on different platforms or in different directories.

When a built in SVG is added to a composer layout using the "add image" button, the path to the SVG is currently stored in the .qgs file as an absolute path or as a path relative to the .qgs file, depending on the project configuration. This is bad - if you open the composer layout on a system where QGIS is installed to a different location then the SVG is missing. If the SVG is built in, the path should be stored relative to the QGIS install directory. If the SVG is in one of the user-defined paths then it should be stored relative to that location.

The code changes for #13214 might be a helpful reference

When a built in SVG is added to a composer layout using the "add image" button, the path to the SVG is currently stored in the .qgs file as an absolute path or as a path relative to the .qgs file, depending on the project configuration.

Now it is always stored as an absolute path.
