Tab on header does not scroll the table body

preciousmind

I am using the latest version of datatables. The table has many columns and displays a horizontal scroll bar. When I use mouse to drag the scroll bar to the right, the columns and headers are getting aligned correctly. However, when I use tab key to move along the column headers to the right, the table body does not scroll, only header part is moving to the right. This is causing issue for keyboard only users.

**Here is a demo of the issue. **

any ideas or help would be appreciated.

Thanks,
