            Bug ID: 145407
           Summary: JavaScript WebKitCSSMatrix 'rotate' method on iOS
                    generates matrix different than the method in other OS
    Classification: Unclassified
           Product: WebKit
           Version: 525.x (Safari 3.2)
          Hardware: iOS
                OS: iOS 8.2
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org

js fiddle testbed: http://jsfiddle.net/DamianS1987/c5c0r4y6/18/

The above js fiddle testbed using WebKitCSSMatrix constructor and 'rotate' method generates following strings:

-iOS (8.3) ipadMini (Safari,Chrome) or ipad 3 retina iOS (8.3)
matrix(0, 0.258819, 0, 0.965926, 0, 0);

-Mac Yosemite, Win8.1, Android (any browser)
matrix(0.965926, 0.258819, -0.258819, 0.965926, 0, 0);

Now most major devices work well. However, ipad (tested on two different devices) generates matrix with 'a' and 'd' values equal to 0 - transform: matrix(a, c, b, d, tx, ty).
