JSON.parse fails with tab in property name

[mus65]

Consider the following JavaScript file test.js:

JSON.parse("{\"abc\\tdef\": \"42\"}");

Note that the property name contains a \t . The following code will fail:

var engine = new Jint.Engine();
engine.Execute(File.ReadAllText(@"TestFiles\test.js"));

Exception:

Jint.Runtime.JavaScriptException: Invalid character in property name 'abc	def'
   at parse <anonymous>:1:1
   at <anonymous>:1:1

The same code works fine in Edge:

This only seems to affect property names, tabs in values work fine.
