Virtual Grid - Horizontal and Vertical Scrollbar don't work together

[chughes-lincoln]

If you have a dataset with a lot of fields, or with a lot of information in those fields, a horizontal scrollbar will appear to render all of the data. If you scroll to the right of the grid, and then scroll down, the grid will continue scrolling to the bottom of the grid even after the user has stopped scrolling.

On the demo css this doesn't come across as frequently, as the grid cells re-size dynamically based on the cell content, so the horizontal scrollbar doesn't appear as often. It does prevents the admin from setting a minimum width in the css if they prefer consistent widths with the scrollbar.
