Highcharts Gantt Vertical Scrollbar Missing in Full Screen Mode

I'm having an issue with Highcharts Gantt 8.0.0 when viewing in fullscreen mode where the vertical scrollbar seems to be missing. 

Highcharts.ganttChart('gchart-container', {
     // ... among other options, here are the related 
     // scrolling / exporting options being used

    scrollbar: {
       enabled: true
    },
    exporting: {
            enabled: true,
            // just trying a few different things here ... 
            chartOptions: {
                xAxis: [{
                    max: null
                }]
            },
            accessibility: {
                enabled: true
            },
            menuItemDefinitions: {
                "viewFullscreen" : { 'text': 'View Full Screen'},
                "downloadPDF": { 'text' : 'Download PDF'},
                "downloadPNG": { 'text' : 'Download PNG'},
                "downloadJPEG": { 'text' : 'Download JPEG'}
            },
            buttons: {
                contextButton: {
                    menuItems: ['viewFullscreen', 'separator', 'downloadPDF', 'downloadPNG', 'downloadJPEG']
                }
            }
    },
});

There is no issue when viewing the chart in normal mode as it's rendered in the DOM's #gchart-container div (notice the browser's vertical scrollbar on the right).

Conversely, when clicking the export button and selecting "View in Fullscreen" I have full functionality of the task hierarchy (expanding/collapsing) but vertical scrolling is disabled or removed...

Any ideas on how to enable vertical scrolling during exporting/fullscreen mode? Thank you in advance!
