#32305: Emoji script is producing errors on pages with SVG content

--------------------------+-----------------------------
 On pages that contain dynamic SVG content, such as charts generated by
 JavaScript, Emoji script wp-emoji-release.min.js produces multiple errors
 like this:

 ''Uncaught TypeError: node.className.indexOf is not a function''

 The error is caused by the script traversing through document nodes, going
 into SVG nodes and checking indexOf of their className which is not a
 function, resulting in JS error reported on every SVG <path> node.

 The error originates in this line: (taken from unminified version)

 {{{
 if ( ! node || ( node.className && node.className.indexOf( 'wp-exclude-
 emoji' ) !== -1 ) ) {
    continue;
 }
 }}}
