Qt Quick 3D RuntimeLoader should have a "pickable" property

RuntimeLoader {
    id: loader
    source: "..."

    function makeChildModelsPickable(node) {
        if (node?.pickable !== undefined) // Only Models have a `pickable` property defined
            node.pickable = true
        node.children.forEach(childNode => makeChildModelsPickable(childNode))
    }

    Component.onCompleted: makeChildModelsPickable(loader) // Mark the model at startup
    onSourceChanged: makeChildModelsPickable(loader) // Mark the model each time we change the source file
}
