Problem description: Changing Panel2MinSize in a horizontally oriented SplitContainer (Panel2 below Panel1) changes the SplitterDistance if Panel2MinSize > Panel2.Width.
Expected behavior: SplitContainer should respect its Orientation when changing Panel2MinSize. Changing Panel2MinSize in a horizontally oriented SplitContainer (Panel2 below Panel1) should only change the SplitterDistance if Panel2MinSize > Panel2.Height.
Minimal repro:
var form = new Form() { Size = new Size(200, 500) };
var splitContainer = new SplitContainer() { Orientation = Orientation.Horizontal };
splitContainer.Dock = DockStyle.Fill;
form.Controls.Add(splitContainer);
form.Show();
Debug.WriteLine(splitContainer.Panel2MinSize); // 25
Debug.WriteLine(splitContainer.Panel2.Height); // 227
Debug.WriteLine(splitContainer.SplitterDistance); // 230
splitContainer.Panel2MinSize = 205;
Debug.WriteLine(splitContainer.Panel2MinSize); // 205
Debug.WriteLine(splitContainer.Panel2.Height); // 269 (should be 227)
Debug.WriteLine(splitContainer.SplitterDistance); // 188 (should be 230)
