           Summary: Consecutive animateTransform of an SVG shape does not
                    work
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh Intel
        OS/Version: Mac OS X 10.8
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: SVG
        AssignedTo: webkit-unassigned at lists.webkit.org

If I try to animate one object twice consecutively, it ignores the second one most of the time (It doesn't seem to be deterministic). 

In following example the rect should move periodically up and down. Works as expected in Firefox and Opera, not in Chrome, Safari. Tried also current nightly build 537.33+, didn't work either. In webkit it only goes downwards (anim1a) with a delay after each movement.

    </rect>
</svg>
