           Summary: WebKitCSSMatrix inconsistent behavior
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: UNCONFIRMED
          Severity: Critical
          Priority: P1
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: webkit at rokajak.dk


There is a bug in the JavaScript WebKitCSSMatrix object; the following example explains:

var A = new WebKitCSSMatrix();
var B = new WebKitCSSMatrix();
var C = A.multiply(B);
Result on Mobile Safari:
C = B.A
Result on Desktop Safar:
C = A.B

Notice that B.A is calculated different than A.B, and therefore the result is not likely to be the same!
