Hello,

We are very sory for the late response. Unfortunately, this is not a bug. When using Iframe scenario, you will need to change menu window type of contextmenu as normal.
Normally in IE, it supports 2 types such as popup and normal. In other browsers, popup is not supported.
To change the type, you will need to handle it OnContextMenu clientside events in WebDesktopManager.

Here is the snippet code:

function WebDesktopManager1_OnContextMenu(controlId, objectType, contextObject, menu)
{
            var WebDesktopManager1 = ISGetObject(controlId);
            menu.MenuWindowType = "Normal";
            return true;
}
