[Enhancement] Similar to Firefox, allow using the scroll wheel to scroll the tab bar when you have enough tabs open that it cannot fit them all on-screen
Simply put, just like in Firefox, when you have many tabs open to the point that it makes the tab bar scrollable, allow the user to use their scroll wheel to scroll the tab bar itself (not switch tabs) when their mouse cursor is hovering over the tab bar.
This scrolling action should ideally go in the same direction as Firefox which itself already goes in the same direction as when you use your scroll wheel on Xfce's bottom panel to switch between open windows.
