Top Sites feature in Safari loads website repeatedly

Top Sites feature in Safari generates pageview(s) by repeatedly loading indexed sites

We’ve noticed that the Top Sites feature in Safari sometimes generates a pageview when Top Sites are displayed. We confirmed this by noticing that we were “generating” visits and pageviews (clicks) to a site that we were not visiting.

The explanation for the reason that our profile kept showing up in the stats is that the site was being disaplyed repeatedly in Top Sites.

This is potentially problematic because it might give the false impression that a person was visiting on a regular basis.
We assume that this happens when Safari generates the Webpage Preview Images.
Definition of Top Sites from Apple website:

Top Sites: Safari automatically identifies your favorite sites and displays them as a wall of graphic previews. To visit one of your top sites, just click any of the previews.
