Fabric: CompileOnly mode missing common assets

[Flemmli97]

Fabric runs are missing all assets from the common project when choosing to use compileOnly mode.
This does not happen for (neo)forge end.
Below is the snippet causing it. If i remove the parts below then it will work fine.

allprojects {
    [...]
    architectury {
        compileOnly()
    }
    [...]
}

subprojects {
    [...]

    if (project.path != ':common') {
        loom {
            mods {
                main {
                    sourceSet project.sourceSets.main
                    sourceSet project(':common').sourceSets.main
                }
            }
        }
    }
}
