我的WPF应用程序使用简单的Menu：
<Menu Name="menuColor" Margin="0,5,0,0">
<MenuItem Name="menuItemHeader" Header="Color" Style="{StaticResource MenuItemHeaderDefaultStyle}">
<MenuItem.Icon>
<Image Name="ButtonImageColor" Source="pack://application:,,,/Resources/update_black.ico" Height="12" Width="12"/>
</MenuItem.Icon>
<MenuItem Name="miBlue" Header="Blue" Click="miBlue_Click" Background="Transparent" Style="{StaticResource MenuItemDefaultStyle}">
<MenuItem.Icon>
<Image Name="miBlueImage" Source="pack://application:,,,/Resources/ok_mark2.png" Height="12" Width="12"/>
</MenuItem.Icon>
</MenuItem>
</MenuItem>
</Menu>
因此，在我的标题栏中，我有Color个文字，点击后我会选择Blue。
因此，我想添加Color而不是icon文本，而目前我看不到我的图标。
我也尝试删除Header="Color"，但仍然看不到我的icon。

<ColumnDefinition Width="Auto" SharedSizeGroup="MenuItemIGTColumnGroup"/>
