Failed to load resource: Frame load interrupted on every export action

[zmoddynamics]

Prerequisites

• [x] I have searched for similar issues in both open and closed tickets and cannot find a duplicate.
• [x] The issue still exists against the latest master branch of yii2-grid.
• [x] This is not an usage question. I confirm having gone through and read the documentation and demos.
• [x] This is not a general programming / coding question. (Those should be directed to the webtips Q & A forum).
• [x] I have attempted to find the simplest possible steps to reproduce the issue.
• [ ] I have included a failing test as a pull request (Optional).

Steps to reproduce the issue

1. Install the extension
2. Configure the plugin as module:

'modules' => [
    'gridview' =>  [
           'class' => '\kartik\grid\Module'
    ]
]

and with export features for example in view file

 <?= GridView::widget([
        'dataProvider'=> $dataProvider,
        'filterModel' => $searchModel,
        'columns' => $gridColumns,
        'autoXlFormat' => true,
        'bootstrap' => true,
        'panel' => [
            'type' => GridView::TYPE_PRIMARY,
            'heading' => '<i class="fa fa-laptop"></i>  Jobs',
        ],
        'toolbar' => [
            [
                'content'=>
                    Html::button('<i class="fa fa-plus"></i>', [
                        'type'=>'button',
                        'title'=>Module::t('kvgrid', 'New Job'),
                        'class'=>'btn btn-success'
                    ]) . ' '.
                    Html::a('<i class="fa fa-repeat"></i>', [''], [
                        'class' => 'btn btn-default',
                        'title' => Module::t('kvgrid', 'Reset Grid')
                    ]),
            ],
            '{export}',
            '{toggleData}'
        ],
        'export' => [
            'fontAwesome' => true,
            'target' => GridView::TARGET_SELF
        ],
        'responsive'=>true,
        'hover'=>true,
        'bordered' => true,
        'striped' => true,
        'condensed' => true,
    ]);?>

3. Click export menu on any of the export types (TXT, JSON, CSV, Excel, etc.) and observe the Javascript Console. The file is generated and download but the Javascript console shows an error each time.

Expected behavior and actual behavior

When I follow those steps, I see... Failed to load resource: Frame load interrupted (Safari)

I was expecting... No errors
