WPF ProgressBar Width not sizing to Text

I am having an issue with the Microsoft WPF ProgressBar. I will set Width="Auto" and the width will size to the text width until a value property of ~97. Between values 97 and 100 the control will go exponentially larger until it hits MaxWidth.

The following style is setting the template for the ProgressBar. I can't seem to find anything that will cause it to behave until a Value of ~97. I do not touch the width in the code behind.

<Style x:Key="CurrentDayProgressBar"   TargetType="{x:Type ProgressBar}">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type ProgressBar}">
                <Grid>
                    <Border Name="PART_Track" CornerRadius="2" Background="DarkGray" BorderBrush="{DynamicResource TextBrush}" BorderThickness="1" />
                    <Border Name="PART_Indicator" CornerRadius="2" Background="{DynamicResource ProgressBarBackground}" HorizontalAlignment="Left" Margin="2" />
                    <TextBlock Name="PART_Text" Margin="2" Width="Auto" Padding="5,0,5,0" Text="{Binding RelativeSource={RelativeSource AncestorType=ProgressBar}, Path=Tag}" 
                               Foreground="Black" HorizontalAlignment="Center" VerticalAlignment="Center" Style="{DynamicResource SimpleTextBlock}"/>
                </Grid>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

The first image below is what the bar looks like when it is at a Value of 99.2. The second is my implementation in the Telerik RadProgressBar, which behaves like I expect it to. The Telerik solution may be what I have to go with, but it would be nice to know why the Microsoft control is not working.

The PART_Track cannot have any extra margins/borders attached to it and/or the PART_Indicator should be nested inside it. To resolve the problem you're having, do something like:

<Border CornerRadius="2" Background="DarkGray" BorderBrush="{DynamicResource TextBrush}" BorderThickness="1" />
<Border x:Name="PART_Track" Margin="3">
    <Border Name="PART_Indicator" CornerRadius="2" Background="{DynamicResource ProgressBarBackground}" HorizontalAlignment="Left" />
</Border>    
<TextBlock  ... />
