+        Video previews on shutterstock.com don't play when tapped on iPadOS

+        Reviewed by Wenson Hsieh.
+
+        When tapping on a video preview after searching for a video on shutterstock.com, for instance on https://www.shutterstock.com/video/search/people,
+        we correctly enter the hover state thanks to our content observation heuristics, but the <video> preview inserted fails to play and show due to a
+        style rule setting a "display: none" style if the media-query "pointer: coarse" evaluates to true.
+
+        In order to improve this website's behavior on iPadOS, we add a new quirk that prevents the "pointer: coarse" media query from evaluating to true.
+        This new quirk, shouldPreventPointerMediaQueryFromEvaluatingToCoarse(), evaluates to true only for this this website.
