Section mounted programmatically is not given id if not specified explicitly

[AleksueiR]

const dvChart = new DQV.Chart({
    id: 'nuclear',
    config: sample3chartConifg
});

const dvSection = new DQV.Section({
    data: sample3data,
    // id: 'sample3',
    template: sample3template,
});

dvSection.mount(document.getElementById('sample3target'));

The section is given undefined as an id. This shouldn't happen; an auto-generated id should be provided.
