Offline Export button does nothing

[coredan]

The export button (that appears on the right) does nothing. No clickable.

That is my test code:

<?php 
use miloschuman\highcharts\Highcharts;
use yii\web\JsExpression;
?>
<?= Highcharts::widget([
    'scripts' => [
        'modules/exporting',
        'modules/offline-exporting',
        'modules/export-data',
        'themes/dark-unica',
        //'themes/grid-light',
    ],
    'options' => [
        'credits' => ['enabled' => false],                                
        'exporting' => [
            'enabled' => true,
            'chartOptions' => [ // specific options for the exported image

                        ]
                    ]
                ]
            ],

Charts loads OK. Theme loads OK. Scripts loads OK (at the end of the page):

My mistake. I had a CSS rule that disabled the button: pointer-events: none;

Sorry.
