Summary: When a drag hovers over a UIPageController that's configured to scroll horizontally, it will randomly scroll, often into blank space. Steps to Reproduce: Open and run the attached project Drag the view a little (the bug does not trigger if the page controller has never been scrolled) Select the text in the text-field Hold it do start a drag Wiggle the drag over the screen for a few seconds Expected Results: The page-controller should not respond to the hovering drag. Actual Results: The page-controller rapidly scrolls by some offset - often the page width, sometimes less. This often takes it into blank space. Version/Build: Xcode 9.0 (9A235) iOS SDK 11.0
