mouseover not showing pointer icon and link indicator for clicking

Note: I have tried this on my test website which uses twentythirteen theme and no plugins with the same result.

Here's a URL if you want to see for yourself:

When on the grid, and you mouse over in image, it changes to the pointer hand and shows the link indicator.

When on an individual product page, it doesn't show the pointer hand or the link indicator.

Please advise.
