Start by running the attached LayoutIssue.zip sample on Windows and follow the listed steps with the StackLayout height and width requests. Compare the default layout near the page title with the layout while resizing the window. Done means the ListView and other StackLayout children no longer overlap the title or extend beyond the window.
