    RadMenu1.RenderMode = RenderMode.Mobile;
    RadMenu1.Width = 300;
    for (int i = 0; i < 10; i++)
        var radmenuItem = new RadMenuItem();

The issue seems to be related to how the browser handles the jQueryAnimations that are used internally. 

One option to work around this is to disable the Expand animations by setting the Menu's ExpandAnimation-Type property to "None"

The following workaround should allow you to fix the issue without disabling the animations: 

var old_transition = $telerik.transition;
$telerik.transition = function (element, properties, duration, easing, complete) {
    if (!complete) {
        complete = function () {
            $telerik.$(".RadMenuPopup .rmToggle").hide().show();
    }, element, properties, duration, easing, complete);
