mybe you are doing it wrong way...

    <hc:Window.NonClientAreaContent>
        <Grid>
            <Grid.ColumnDefinitions>
                <ColumnDefinition/>
                <ColumnDefinition/>
            </Grid.ColumnDefinitions>
            <StackPanel Height="29">
                <Menu HorizontalAlignment="Left">
                    <MenuItem Header="Header1">
                        <MenuItem Header="Header1"/>
                        <MenuItem Header="Header2"/>
                    </MenuItem>
                    <MenuItem Header="Header2">
                        <MenuItem Header="Header1"/>
                        <MenuItem Header="Header2"/>
                    </MenuItem>
                </Menu>
            </StackPanel>
            <Button HorizontalAlignment="Right" Grid.Column="1" Name="ButtonConfig" Style="{StaticResource ButtonIcon}" Foreground="{DynamicResource PrimaryTextBrush}" hc:IconElement.Geometry="{StaticResource ConfigGeometry}"/>
            
        </Grid>
    </hc:Window.NonClientAreaContent>

The reason for the problem is that I did not use Grid, but directly used hc:SimpleStackPanel.
