13656	Review a revert done to yui-3.17.1-dom-screen-node-core*	Olek Nowodziński	Piotrek Koszuliński	In git:de679b432f6 I reverted some changes done in #13265 because it caused problems in `tests/core/dom/element/element` (getDocumentPosition failed) in IE8. We must ensure that what I did is safe considering the scope of #13265.	Task	closed	Normal	CKEditor 4.5.4	General	4.5.3	fixed
