Research direction

The issue is about the horizontal scrollbar in the terminal tabs area being too thick and only appearing on hover. The fix likely involves adjusting CSS styles for the scrollbar in the terminal widget. Look for the terminal's CSS files in theia/packages/terminal or similar. Consider adding a custom scrollbar style that is thinner and always visible. Check existing scrollbar styling in other parts of Theia for consistency. The issue has no assignee or linked PR, so it's open for contribution.
