Dashboard plugin: HTML5 error in v4.0.8, DFN tag and "tooltip" attribute

RE: wpmudev-updates\template\support-demo.php

Lines 563, 566, 572

The <dfn> tag is given an invalid "tooltip" attribute. Use the title attribute, and escaping the embedded HTML might help as well. Example:

<dfn title="& lt; p & gt; & lt; big & gt;... & lt; /big & gt; & lt;/p & gt;">BIG TEXT</dfn>

( I had to embed spaces in there - no matter what else I did, the escaped characters were converted. )
