I ran into this exact same problem. I was able to circumvent it by first using the deprecated Xml.parse, since it still works, then selecting the body XmlElement, then passing in its Xml String into the new XmlService.parse method:

var page = UrlFetchApp.fetch(contestURL);
var doc = Xml.parse(page, true);
var bodyHtml = doc.html.body.toXmlString();
doc = XmlService.parse(bodyHtml);
var root = doc.getRootElement();

Note: This solution may not work if the old Xml.parse is completely removed from Google Scripts.
