Scroll bar not appearing in auto complete control



User is fetching the details from a data table and displaying on the screen using Auto-complete control.

When the user clicks on down arrow without entering any characters, then all the results are coming and vertical scroll bar is appearing.

Once the user starts typing some characters, as expected, the results are getting filtered but even though there are more results, the vertical scroll bar is not coming.
