Looks like the animated property cache doesn't get purged. The only code attempting to remove stuff is ~SVGAnimatedProperty() but it appears to never kick in (are we keeping all animated props referenced indefinitely?).

To make matters worse, the cache is global so it doesn't get purged even on page reloads.
