C# WPF DataGrid调整内部列标题的大小会导致极端的滚动

我发现了一个关于股票WPF数据网格的行为，我无法解释或阻止，但它感觉像一个bug。我很好奇是否有人遇到过这种情况，以及解决方法是什么

复制步骤：

当使用具有多个列的DataGrid（在我的测试应用程序中为4列）时，请调整标题大小，以便显示水平滚动条

一直向右滚动

开始调整不是第一列或最后一列的任何列的大小

将列向左调整到最小值

然后将其向右拖动，您将看到该列的大小已调整为最大宽度

要使列恢复到适当的大小有些困难。下面是一个简单的WPF应用程序，用于演示该问题

MainWindow.xaml

<Window x:Class="TestGridColumnSpacing.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:TestGridColumnSpacing"
        mc:Ignorable="d"
        Title="MainWindow"
        Height="450"
        Width="750">

    <Grid>
        <DataGrid x:Name="TheDataGrid" AutoGenerateColumns="False">
            <DataGrid.Columns>
                <DataGridTextColumn Header="Field 1" Binding="{Binding Field_1}" />
                <DataGridTextColumn Header="Field 2" Binding="{Binding Field_2}" />
                <DataGridTextColumn Header="Field 3" Binding="{Binding Field_3}" />
                <DataGridTextColumn Header="Field 4" Binding="{Binding Field_4}" />
            </DataGrid.Columns>
        </DataGrid>
    </Grid>
</Window>

我一直在寻找一个解决方案或其他开发人员谈论它，但我找不到任何提及，这是令人惊讶的，因为它是多么容易复制。请分享您关于解决方案的所有信息

namespace TestGridColumnSpacing
{
    using System.Windows;

    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();

            this.Loaded += MainWindowLoaded;
        }

        private void MainWindowLoaded(object sender, RoutedEventArgs e)
        {
            this.TheDataGrid.Items.Add(new { Field_1 = "", Field_2 = "", Field_3 = "", Field_4 = "Step 1: Using right thumb on Field 4 header, resize enough to make horizontal scrollbar visible if not visible already." });
            this.TheDataGrid.Items.Add(new { Field_1 = "", Field_2 = "", Field_3 = "", Field_4 = "Step 2: Scroll horizontal scrollbar entirely to the right." });
            this.TheDataGrid.Items.Add(new { Field_1 = "", Field_2 = "", Field_3 = "", Field_4 = "Step 3: Using right thumb of Field 3, resize to the right.\nThis will increase the width of Field 3. Notice normal manner of the scrollbar's size changing." });
            this.TheDataGrid.Items.Add(new { Field_1 = "", Field_2 = "", Field_3 = "", Field_4 = "Step 4: Using right thumb of Field 3, resize the column leftward until Field 3 approaches its minimum width.\nYou'll notice when all of Field 4 is in view, Field 3 will continue to collapse and appear to shrink towards Field 4." });
            this.TheDataGrid.Items.Add(new { Field_1 = "", Field_2 = "", Field_3 = "", Field_4 = "Step 5: At this point, continue using the right thumb of Field 3 to resize the column.\nNotice exaggerated resizing of the scrollbar."});
        }
    }
