工具条带控件主机的AutoSize不能正常工作

Question

在下面的代码中，当按钮被按下时，我试图在按钮上方显示一个弹出窗口，但ToolStripControlHost的AutoSize不能正常工作，并且不会显示整个内容。除此之外，即使指定了按钮位置，弹出窗口也会显示在按钮上方。我该如何解决这个问题？

namespace WindowsFormsApp7
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            var panel1 = new Panel();

            var label1 = new Label();
            label1.Text = "12345\nabsde\nlllllllllllllllllA\nVWXYZ\nZZZZZZZZZZZZZZA";
            label1.BackColor = Color.Red;
            label1.Margin = Padding.Empty;
            label1.AutoSize = true;
            label1.Size = Size.Empty;
            label1.Location = new Point(0, 0);
            panel1.Controls.Add(label1);

            var toolStripControlHost = new ToolStripControlHost(panel1);
            toolStripControlHost.Margin = Padding.Empty;
            toolStripControlHost.Padding = Padding.Empty;
            toolStripControlHost.BackColor = SystemColors.Info;
            toolStripControlHost.AutoSize = true;
            toolStripControlHost.Size = Size.Empty;

            var toolStripDropDown = new ToolStripDropDown();
            toolStripDropDown.Margin = Padding.Empty;
            toolStripDropDown.Padding = Padding.Empty;
            toolStripDropDown.DropShadowEnabled = false;
            toolStripDropDown.AutoSize = true;
            toolStripDropDown.Size = Size.Empty;
            toolStripDropDown.Items.Add(toolStripControlHost);
            toolStripDropDown.Show(this, button1.Location, ToolStripDropDownDirection.AboveRight);
        }
    }
}

我注意到在将控件插入到toolStripControlHost中时，字体会发生变化，因此我插入了以下代码来尝试并使字体显式显示，现在它工作得很好。

toolStripControlHost.Font = DefaultFont;
