How to get WPF GridSplitter to resize my grid?

WPF GridSplitter makes my grid wider than my window!

I have a WPF Grid with a GridSplitter. If I resized my columns, then I can make the grid wider than my window and cannot be viewed.

It starts as follows:

But after expanding the left column, I can no longer see the right column (green):

What am I doing wrong? How to make GridSplitter resize my grid?

Update:

I'm still struggling with this. Now I have tried nested grids in meshes. It did not help. Here are my XAML ColumnDefinitions, RowDefinitions and GridSplitters ...

            <ColumnDefinition Width="*" MinWidth="400" />
        </Grid.ColumnDefinitions>
        <GridSplitter 
            ResizeDirection="Columns"
            ResizeBehavior="BasedOnAlignment"
            Grid.Column="1"
            HorizontalAlignment="Center"
            VerticalAlignment="Stretch"
            Width="2"
            Margin="0,5,0,5"
            Panel.ZIndex="1"/>
        <Grid Grid.Column="0">
            ...
        </Grid>
        <Grid Grid.Column="2">
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="*" MinWidth="150" />
                <ColumnDefinition Width="Auto" />
                <ColumnDefinition Width="*" MinWidth="200" />
            </Grid.ColumnDefinitions>
            <GridSplitter 
                ResizeDirection="Columns"
                ResizeBehavior="PreviousAndNext"
                Grid.Column="1"
                HorizontalAlignment="Center"
                VerticalAlignment="Stretch"
                Width="2"
                Margin="0,5,0,5"
                Panel.ZIndex="1"/>
            <Grid Grid.Column="0">
