With handleNew: wrapper, this example:

new WeakMap

turns into:

handleNew.box($S.g.WeakMap)

while the expected behavior is leaving the code alone.

The issue is that useGlobalObject breaks the logic used to leave the code unwrapped since WeakMap turns to $S.g.WeakMap.

This works fine for most built-ins, but breaks when I tried to use Event.

P.S. The logic here is redundant.
