           Summary: SVG animations do not support dynamic condition
                    targets
           Product: WebKit
           Version: 420+
          Platform: Unspecified

Testcase

Consider this example:

<rect id="rectRed" width="100" height="100" x="0" y="0" fill="red"/>
<rect id="rectGreen" width="100" height="100" x="100" y="0" fill="green"/>
<set id="set" attributeName="x" to="0" xlink:href="#rectRed" begin="click"/>

<script>
var animation = document.getElementById('set');
animation.setAttributeNS('http://www.w3.org/1999/xlink', 'xlink:href', '#rectGreen');
</script>


When we move the animation target from the red rect to the green rect, the click animation condition should move too but it does not. This currently works in Firefox and Opera.

A related issue is detecting dynamic id changes such as if "blueRect.click" was used as the begin condition and blueRect's id was changed. One way to fix these issues would be to add condition targets to our target tracking infrastructure in SVGDocumentExtensions.
