hc:SideMenu侧边菜单通过代码修改选中项，无法触发鼠标的事件怎么办？

Feature request type

enhancement

Is your feature request related to a problem? Please describe

我想通过点击一个按钮而不是菜单进行修改侧边菜单的选中状态，代码中sideMenuItem.IsSelected = true;修改后，无法触发sideMenuItem中受保护的OnSelected方法，导致我再次点击原先菜单项发现选中状态同时出现两个选中的。

Describe the solution you'd like

我想从某个页面中的按钮点击，然后修改菜单选中状态，如何实现呢？

                        {
                            sideMenuItem.IsSelected = true;
                        }
                    }
                }
            }
        }
    }
}

}

Start by inspecting the SideMenu and SideMenuItem selection handling, including the protected OnSelected method, then reproduce the behavior with the provided UpdateSideMenuSelected method. Done means selecting an item from code produces the same selection behavior as a mouse click and does not leave multiple items selected.
