Una soluzione potrebbe essere, ridurre la dimensione del MARQUEE ed inserirlo in un DIV dimensionato.
codice:
<html>
<head><title>MARQUEE inside DIV</title>
</head>
<body style="margin: ;">
<div style="height: 893px; width: 200px; background-color:#E4E4E4; border: 1px dashed red;">
<marquee id="news" scrolldelay="-5" behavior="scrol" direction="up" scrollamount="3" loop="-1"
width="200px" height="500px"
style="background-color:#E4E4E4; border: 1px dashed blue">
....
</marquee>
</div>
</body>
</html>
