How to set the class name of the global object

[tbl...@icloud.com]

I'm trying to get behavior similar to that of the global object in a Chrome JavaScript context through the V8 API. I've created a FunctionTemplate, called SetClassName on the template, set various properties on its PrototypeTemplate and InstanceTemplate, and then used the InstanceTemplate to create a context. However, when I run Object.prototype.toString.call(this), I get [object Object], instead of what I set the class name to. How does Chrome make it so that Object.prototype.toString.call(this) is [object Window]?

Thanks,

I don't know if Chrome does it in C++ or JS but it executes the moral
equivalent of:

Object.defineProperty(this, Symbol.toStringTag, { configurable:
true, value: 'Window' });

Interesting. Out of curiosity, how did this work before Chrome added support for Symbol.toStringTag?

Previously we used the class name.
