I think that adding a custom property on each node in WeakMap may be a reasonable workaround. Geoff, does this have any serious downsides?
while (i--) {
document.body.appendChild(document.createElement('p'));
document.body.lastElementChild.textContent = i;
document.body.lastElementChild.webkitWeakMapWorkaround = 1; // <-- This
wmap.set(document.body.lastElementChild, { foo: 'bar', id: i });
}
Perhaps we can use a similar mechanism to make WeakMap work with nodes. Possibly a side HashCountedSet, or even a counter in node rare data.
