You need custom scripts enabled.

var doc=top.noodle.headWindow().document;
var newNode =doc.getElementById("logo");
doc.body.insertBefore(newNode, doc.body.firstChild);
top.document.getElementById("body").rows="110,0,*";
newNode.style.position="inherit";
newNode.style.height="55px";
newNode.style.width="100%";

or you can use an image hosted elsewhere:

var doc=top.noodle.headWindow().document;
doc.getElementById("logo").style.display="none";
var newNode = doc.createElement('img');
newNode.src="https://vialect.com/wp-content/themes/quadro/images/logo.png";
newNode.style.height="55px";
newNode.style.width="100%";
doc.body.insertBefore(newNode, doc.body.firstChild);
top.document.getElementById("body").rows="110,0,*";
