Panel box shadow

I have a listview element in a panel and noticed that the box shadow does not go over the listview. It starts where the listview ends about a third the way down the panel.

This makes the effect look broken.I have tried to play with z-index but got no results.

.ui-panel-display-reveal {
box-shadow: -5px 0 5px rgba(0, 0, 0, 0.15) inset;
}
