另外，可能是因为使用MouseGesture的原因，有时候点击ComboBox不会展开下拉框。
我目前的处理方法是在OnToggleGestureChanged里写一个是否需要触发下拉的标记，然后继承OnMouseLeftButtonDown方法，在这个标记启用的时候切换IsChecked。

In addition, maybe because of the use of MouseGesture, sometimes clicking the ComboBox will not expand the drop-down box. My current method is to write a tag in OnToggleGestureChanged to determine whether the drop-down needs to be triggered, and then inherit the OnMouseLeftButtonDown method to switch IsChecked when the tag is enabled.

this happens, with the combobox dropdown auto closes and only is open until I don't lift mouse button,
