 While running the Press This feature category through HTML validation, two
 TinyMCE-related errors appeared:

 1. Element link is missing required attribute property originating from
 `<link rel='stylesheet' id='editor-buttons-css'
 href='http://kraftbj.wpsandbox.me/wp-
 includes/css/editor.min.css?ver=4.2-alpha-31438' type='text/css'
 media='all' />` which is being inserted from
 https://core.trac.wordpress.org/browser/tags/4.1/src/wp-includes/class.wp-
 styles.php#L91

 2. Attribute autocomplete not allowed on element textarea at this point
 originating from : https://core.trac.wordpress.org/browser/tags/4.1/src
 /wp-includes/class-wp-editor.php#L235

 For 1, basically, `link` elements, namely with the `rel` attribute, must
 be in the docment's head. All modern browsers support them everywhere.
 Likely a wontfix IMO.

 2: I'm not sure why this is being triggered.

 Didn't see an existing ticket, so wanted a point of reference, even if
 they're both acceptable and wontfix.
