thistest case doesn't work either

Both original code and patched code can pass this test case.
I debugged webkit:

(gdb) bt

in WebCore::SMILTimeContainer::updateAnimations():
Line 260:           for (unsigned n = 0; n < toAnimate.size(); ++n) {
toAnimate is always empty, so  
Line 285:         animation->progress(elapsed, resultElement); 
never be called.
