 Elements are styled in such a way that they don't overlap visually
 unless they also overlap structurally.
 This file is designed to be opened from test_bug199692.html in a popup
 window, to guarantee that the window in which document.elementFromPoint runs
 is large enough to display all the elements being tested.
