Ok.. this is way too general but i think this bug left unnoticed and gave path to many bugs that related to IE11 regarding performance. to prove my point we can reproduce this very easily using `UI Responsivess` tab in IE11 developer tools. Duplicate the amount of ` :not` selectors prefixed with space and measure the time it takes for IE to calculate layout(in green).
