I am having issues with the following script as the zoom function does not work at all. I am attempting to zoom out so we can see all three bubbles, but it continues to zoom in only on one no matter what I adjust the Zoom to. Any help would be highly appreciated in resolving this weird issue.

Here is the code:

/**
 * Module: Maps
 * Functions for Google Map instances. Called in mg_load_scripts()
 */

const gmap_utils = require( './gmaps-utils' );
const js_info_bubble = require( 'js-info-bubble' );

function init() {
    var map = new google.maps.Map(
        document.getElementById('contact__gmap'),
        {
            center: { lat: 39.53460115430569, lng: -76.3520661918299 },
            zoom: 7,
            disableDefaultUI: true,
            styles: gmap_utils.getStyles(),
        }
    );

    var contactMap = $("[data-gmap='#contact__gmap']");

    var infoBubble = new InfoBubble({
        map: map,
        content: contactMap[0],
        position: new google.maps.LatLng( 39.53460115430569, -76.3520661918299 ),
        backgroundColor: '#a8de00',
        borderRadius: 0,
        borderColor: 'rgba( 0, 0, 0, 0 )',
        padding: 20,
        arrowSize: 20,
    });

    var dcBubble = new InfoBubble({
        map: map,
        content: contactMap[1],
        position: new google.maps.LatLng( 38.91172021157104, -77.0321827083924 ),
        backgroundColor: '#a8de00',
        borderRadius: 0,
        borderColor: 'rgba( 0, 0, 0, 0 )',
        padding: 20,
        arrowSize: 20,
        disableAutoPan: true,
    });

    var chicagoBubble = new InfoBubble({
        map: map,
        content: contactMap[2],
        position: new google.maps.LatLng( 41.89011800871505, -87.63364960641907 ),
        backgroundColor: '#a8de00',
        borderRadius: 0,
        borderColor: 'rgba( 0, 0, 0, 0 )',
        padding: 20,
        arrowSize: 20,
        minWidth: 280,
        disableAutoPan: true,
    });

    infoBubble.open();
    dcBubble.open();
    chicagoBubble.open();
}

/**
 * Public API
 * @type {Object}
 */
module.exports = {
    init: init
};

I tried to adjust the zoom level but it does nothing at all.
