Issue description

When VisualStylesMode is set to Net11, the accent-colored focus indicator rendered for DomainUpDown and NumericUpDown is thicker than the focus indicator rendered for other text input controls.

The accent-colored focus indicator on DomainUpDown and NumericUpDown appears approximately 1 pixel thicker than the one rendered for TextBox, MaskedTextBox, and RichTextBox, resulting in inconsistent focus visuals across input controls.

Steps to reproduce

1. Create a WinForms application targeting .NET 11.
2. Set VisualStylesMode to VisualStylesMode.Net11.
3. Add the following controls to the Form:

• DomainUpDown
• NumericUpDown
• TextBox
• MaskedTextBox
• RichTextBox

4. Build and run the application.
5. Click each control or use the Tab key to move focus between the controls.
6. Compare the thickness of the accent-colored focus indicator.
