* SUMMARY
Cannot expand "TypeError.prototype" to see its properties.
* STEPS TO REPRODUCE
1. js> TypeError.prototype
2. Try to expand the object
=> Uncaught Exception, empty UI
* INFO
[Error] Uncaught exception in inspector page while dispatching callback for command Runtime.getProperties
TypeError: undefined is not an object (evaluating 'properties.stack.value')
(anonymous function) — ErrorObjectView.js:96
[native code]
(anonymous function) — RemoteObject.js:567
* NOTES
- Apparently the backend thinks that "TypeError.prototype" is an "error" object type.
- Seems like JSInjectedScriptHost::subtype (or WebInjectedScriptHost::subtype) might be returning a subtype even for the prototype. The frontend then treats this like a special Error object instance instead of a generic Object.
