Grid doesn't display in Safari

Please look at the following page:

In FireFox and IE, the grid displays fine. However, in Safari, the row is not displayed.

Can you help me fix this?

Because of used styling ( global css rule which affects elements in grid ) width of container differs in FF and Safari - as result unwanted scroller occurs.
You can try to add next command to the grid init

or fully disable h-scroll by“hidden”

The second method you suggested worked. Thanks!
