+        Followup to r245267: fix some more deprecated uses of -[UIApplication interfaceOrientation]
+        https://bugs.webkit.org/show_bug.cgi?id=197867
+        <rdar://problem/50743963>
+
+        Reviewed by Simon Fraser.
+
+        Add a helper method on WKContentView that asks the view's window's scene for an interface orientation; then,
+        use this helper from various places in WebKit instead of invoking -[UIApplication interfaceOrientation]
+        directly. No change in behavior.
