 I have observed that IE8, emoji don't display in some cases.

 Here is an example: http://output.jsbin.com/punabekoli

 The html for jsbin is the html output of Twenty Seventeen hosted on wp-
 themes.com with a minor modification that one emoji has been adding as the
 first para. (the rainbow flag emoji).

 Screenshot generated here:

 I made this work by adding this code on console log:

 var elements =

 for( var i = 0; i < elements.length; i++ ) {

 This can be resolved by using a test for old browsers such as for IE<=8

 document.all && !document.addEventListener;

 or more generally

 "visibilityState" in document

 and modifying L122 of wp-emoji.js or
