title: Swipe to delete cell causes tableViewHeader to move with cell
body: <p>I have encountered a strange bug with my <code>tableViewHeader</code> on my <code>UITableView</code> in iOS 8. When swiping on a cell to reveal the delete button (standard iOS swipe-to-delete), it moves the <code>tableViewHeader</code> along with the cell that is being swiped. As I swipe the cell, the header moves in the same way that the cell being swiped does. No other cells in the table view are moved, only the header and whatever cell is being swiped. I have tested this on iOS 7 haven't encountered the problem. To me, this seems like a bug with <code>tableViewHeader</code> in iOS 8, being that it only occurs in this version and seems like something that should never occur. I see no reason for the header to ever be included in swipe-to-delete.</p>
