LinkLabel image display abnormally

Liv-Goh commented 2 months ago

.NET version

.NET 9.0 SDK build: 9.0.100-preview.6.24328.19

Did it work in .NET Framework?

Yes

Did it work in any of the earlier releases of .NET Core or .NET 5+?

Yes, this is a regression issue. Not reproduce on .NET 8.0

Issue description

Current Behavior (.NET 9.0):

linkLabel does not display the chosen image.
linkLabel image change when new component added to the form
linkLabel display differently in runtime and designer form
linkLabel display in designer changed after run the project

Expected Behavior (.NET 8.0):

linkLabel display the chosen image.
Adding component to form does not affect the linkLabel image
linkLabel image is consistent on both runtime and designer

Steps to reproduce

Create a WinForms .NET 9.0 project
Add a linkLabel component to the form
Set the linkLabel font larger (e.g. 20) to observe the issue easier
click ... in linkLabel Image property, import an image and click ok
Add random component to the form (observe linkLabel behavior)
Run the project (observe linkLabel behavior)

More Info linkLabel ImageList property have the similar behavior

Scratch project repro:

    private readonly LinkLabel _linkLabel1;

    public Form1()
    {
        InitializeComponent();

        Bitmap bitmap = new Bitmap(100, 100);
        using (Graphics g = Graphics.FromImage(bitmap))
        {
            g.Clear(Color.Red);
        }

        _linkLabel1 = new()
        {
            Font = new Font("Segoe UI", 48F, FontStyle.Regular, GraphicsUnit.Point, 0),
            Image = bitmap,
            Size = new Size(322, 86),
            Text = "linkLabel1"
        };

        Controls.Add(_linkLabel1);
        PerformLayout();
    }

Here is the regex I used to find the other mistaken using:

^\s*using\s[^\(].*;.$\s*{
