I cannot add a twitter widget with this code:

<a class="twitter-timeline" href="https://twitter.com/search?q=%40splashcon" data-widget-id="481777140698869760">Tweets about "@splashcon"</a>
<script>!function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0],p=/^http:/.test(d.location)?'http':'https';if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src=p+"://platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs");</script>

gets rendered as:

<a class="twitter-timeline" href="https://twitter.com/search?q=%40splashcon" data-widget-id="481777140698869760">Tweets about &ldquo;@splashcon&rdquo;</a><br/><script>!function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0],p=/^http:/.test(d.location)?&lsquo;http&rsquo;:&lsquo;https&rsquo;;if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src=p+&ldquo;://platform.twitter.com/widgets.js&rdquo;;fjs.parentNode.insertBefore(js,fjs);}}(document,&ldquo;script&rdquo;,&ldquo;twitter-wjs&rdquo;);</script>
