As of today, it seems the rendering enging of is broken. Simple CSS Styling from the <head> doesn't work anymore:

<meta charset="UTF-8">
<title>Naamloos document</title>

.background {
td {


<table width="100%" border="0" cellspacing="0" cellpadding="0" class="background" height="100">
<td>Doesnt work</td>

Any thoughts? 6 months ago something similar happened, it was indeed a bug where they did an update to the old render-engine from a few years ago.
