+ REGRESSION (r170361): In landscape with UI hidden, fixed position elements at top of screen are too low
+ https://bugs.webkit.org/show_bug.cgi?id=135141
+ <rdar://problem/17627525>
+
+ Reviewed by Benjamin Poulain.
+
+ We can't use the WKWebView's UIScrollView contentInsets to determine the unobscured rect
+ in MobileSafari, because contentInsets can't be changed dynamically while scrolling.
+ To get around this, MobileSafari sets obscured insets instead (but also sets a fixed
+ contentInset).
+
+ So if the client calls _setObscuredInsets:, always use _obscuredInsets to compute the
+ content insets.
+
+ * UIProcess/API/Cocoa/WKWebView.mm:
+ (-[WKWebView _computedContentInset]):
+ (-[WKWebView _setObscuredInsets:]):
