--- Comment #8 from Alexey Proskuryakov <ap at webkit.org> ---
DOM is supposed to guarantee that wrappers stay alive for event listeners to fire. Otherwise, code in the listeners will or will not run semi-randomly depending on whether GC happened, which would be incorrect behavior. GC must not be observable from user code.
