Browse source 
* https://www.ecma-international.org/ecma-262/#sec-IsHTMLDDA-internal-slot
* IsHTMLDDA internal slot is an ECMAScript feature for Web Browsers
* IsHTMLDDA is currently enabled only for test mode (we can enable it later if it is really used by third party app)
* some related operations are optionally fixed
