Pull Request Overview

This PR addresses issue #13539 where the MenuStrip was being obstructed by a UserControl in the DemoConsole application.

• The UserControl is now instantiated with explicit dimensions (350, 100) instead of filling the container.
• The panel's starting height has been reduced from half of tabPage6's height to a third, likely to better accommodate the MenuStrip.

Looks good, thanks!
