Object.prototype.propertyIsEnumerable should accept symbol arguments too #3473

Open theseanl opened 4 years ago

Object.prototype.propertyIsEnumerable defined in es3.js only accepts string type parameter, but it should accept symbols too.

This prevents compiling a line of tslib with Closure Compiler.
