toString(obj) as Symbol.prototype.toString can be overwritten.

We already use Object.prototype.toString in the code. The toString(obj) will not
work:

$> "" + Symbol()
$> TypeError: Cannot convert a Symbol value to a string

wrap it in try-catch

Done, wrapped in a try-catch block.

             // get the real DOM wrapper name from the constructor property.
