TabControl 在标签页数量溢出的时候, 点击右侧菜单, 跳转标签的逻辑不太合理

我尝试修改了一下, 这样可以达到效果. 没有添加动画. 仅供参考.
`
menuItem.Click += delegate
{
_buttonOverflow.IsChecked = false;

                    var list = GetActualList();
                    if (list == null) return;

                    var actualItem = ItemContainerGenerator.ItemFromContainer(item);
                    if (actualItem == null) return;

                    // 获取tabitem 对象在scrollviewer中的位置
                    var targetX = item.TransformToVisual(_scrollViewerOverflow)
                            .Transform(new Point(_scrollViewerOverflow.HorizontalOffset, 0)).X;

                    // 判断tabitem是否已经显示  如果超出scrollviewer当前显示范围的左右两端
                    if (targetX < _scrollViewerOverflow.HorizontalOffset
                    || targetX > _scrollViewerOverflow.HorizontalOffset + ActualWidth - TabItemWidth)
                    {
                        // 直接跳转到目标位置
                        _scrollViewerOverflow.ScrollToHorizontalOffset(targetX);
                    }

                    item.IsSelected = true;
                };`

Locate the TabControl implementation and start with the overflow menuItem.Click handler described in the issue, including GetActualList and _scrollViewerOverflow. Reproduce selecting a tab that is outside the visible overflow range, then verify that selecting a menu item brings it into view without unnecessary movement and leaves it selected.
