I've noticed that in my project, as well as on the online load-on-demand demo's, when the user clicks on expand multiple times, the node generates multiple loading images but only removes one of these images when the child-nodes are returned.
How can I deal with this issue?

You can use the OnClientNodeExpanding and OnClientNodePopulated events to prevent this behavior:
function OnClientNodeExpanding(sender, args) {
var node = args.get_node();
if (node.get_attributes().getAttribute("loading")) {
