+ Require layout when -webkit-overflow-scrolling changes
+ https://bugs.webkit.org/show_bug.cgi?id=120535
+
+ Reviewed by Darin Adler.
+
+ Add a test to ensure we perform a layout and repaint when the
+ value of -webkit-overflow-scrolling changes on an element.
+
+ At the time of writing, the iOS port enables ACCELERATED_OVERFLOW_SCROLLING.
+

+ * fast/repaint/overflow-scroll-touch-repaint.html: Added.
+ * platform/efl/TestExpectations: Skip test fast/repaint/overflow-scroll-touch-repaint.html
