The test was missing an initialization of the global ref variable
because there was also an unused local one, leading to failures
like the one seen in #34625.

The test was missing an initialization of the global `ref` variable
because there was also an unused local one, leading to failures
like the one seen in nodejs#34625.

Ok, now I'm really curious why this wasn't failing consistently in other CI runs! So happy you found this!

I think your PR changes GC timing in some way – previously, the finalizer was run during shutdown, where no JS calls are allowed anyway (i.e. the NAPI_PREAMBLE in napi_throw_error() prevents the function from doing anything but failing). With your PR, the finalizer is scheduled to run from actual GC on some platforms, so it can cause uncaught exceptions in JS.
