Description
Describe the bug
CheckComboBox多选框使用hc:ListBoxAttach.SelectedItems绑定选择项，会报警告找不到源: RelativeSource FindAncestor, AncestorType='HandyControl.Controls.TagContainer', AncestorLevel='1'。且绑定选择的内容可以通过后端更新，通过界面修改后传递过来的值就是null的了
Steps to reproduce the bug
<hc:CheckComboBox
hc:InfoElement.ShowClearButton="True"
hc:InfoElement.Title="筛选条件"
hc:ListBoxAttach.SelectedItems="{Binding SelectConditions}"
ItemsSource="{Binding FilterConditions}"
ShowSelectAllButton="True" />

Research direction
Start with the CheckComboBox usage and the ListBoxAttach.SelectedItems binding shown in the report; reproduce the RelativeSource warning and the null value after a UI change. Done means the binding works without the warning and backend updates and interface changes both preserve the selected values.
