Replacing throw with JsValue.Undefined

[kotbrain]

I am trying to make a NodeList implementation and found a issue. Following the specification:
If index is greater than or equal to the number of nodes in the least, this return null.

However, I get an exception in the ReflectionAccessor.GetValue method and code execution is interrupted.
Index was out of range. Must be non-negative and less than the size of the collection.

I replaced the throw with return JsValue.Undefined and that solved this issue. I could add checks to the NodeList, but it's not an elegant solution. Could you make a fixes to Jint or add customization of this behavior?

Can you show us your code?

I'm using the AngleSharp class.

Test JavaScript code:

var testElement = document.createElement('test');
console.log(testElement.childNodes[1]);

Well that implementation should probably check for valid index in indexer and return null if out of bounds. You could probably copy and modify your own version on your project.
