Description Justin Schuh 2011-02-03 12:17:13 PST
We rebuild the USE element shadow tree on any modification to the target. In the cases like animation we end up constantly destroying and rebuilding the shadow tree. We should look at either more selectively updating the tree or--if possible--not cloning the elements and instead making it an actual shadow with an extra layer to route events.
