--- Comment #1 from Chris Dumez <cdumez at apple.com> ---
The IDBTransaction constructor uses this:
 vm.whenIdle([protectedThis = makeRef(*this)]() {
            protectedThis->deactivate();
        });

It seems our lambda is getting called prematurely here because the JS is using await on a setTimeout.
