I want to display a DFP ad in a slideshow built with the Fotorama plugin. It works fine but the ad disappears in fullscreen or if I am sliding to other frames and back to the ad-frame.  The iframe-document-body becomes empty of the ad-unit. I can solve it with googletag.pubads().refresh([specificSlot]);But I don't want a new refresh/new ad, I want the same ad to be shown again with no extra counting.Can I simply use googletag.display('id-of-ad-unit-div');?
