[M80] Change box-shadow on display panel

The display panel is the container for progress, summary and error panel
items. The box shadow that surrounds the contained entries should be
invisible when there is no child content, and hence, no size.

Change the 'spread' for the CSS box-shadow to stop it drawing when there
is no child content.
