Steps to Reproduce

1. Open a Flutter project in VS Code
2. Run the app on a device/simulator
3. Use the command "Dart: Open DevTools in Browser" from the command palette (Cmd+Shift+P)

Expected Behavior

DevTools should open in the default browser without any additional icons appearing in the macOS Dock.

Actual Behavior

When DevTools opens in Chrome, an unwanted Chrome launcher icon appears and remains in the macOS Dock. This icon is separate from the normal Chrome application icon and clutters the Dock unnecessarily.

Additional Context

• The extra icon only appears when launching DevTools from VS Code
• Opening Chrome normally doesn't create this duplicate icon
• The icon remains in the Dock even after closing the DevTools tab

I suspect this is a browser_launcher issue. I've opened dart-lang/tools#2313
