The STKPages does not calculate the offset right.

Reproduce:

• Add in /demo-project/news-and-events/news-overview three more news pages by copy the existing.
• Configure the news overview components on the /demo-project/news-and-events/news-overview with max results 5.

-> fist pager should display 5 elements, the second one.
Result is, that the first displays two, and the second one.

I think the problem is within the offset calculation in:
info.magnolia.module.templatingkit.util.STKPager.getOffset()
But don't have time to dig into.

Any Components extending the info.magnolia.module.templatingkit.paragraphs.AbstractItemListModel will have this problem:
stkNewsOverview, stkEventsOverview
