You're right - the issue is that the entire row is clickable, which interferes with the tooltip interaction. Let me fix that:

I've fixed the tooltip interaction issue with these changes:

1. Separated the tooltip trigger from the row click area:

   • Made the tooltip trigger a distinct button element
   • Added e.stopPropagation() to prevent the row click event from firing when clicking the tooltip button

2. Made the tooltip icon always visible:

   • The "+N" indicator and info icon are now always visible (not just on hover)
   • Styled them as a clear, interactive button with hover effects

3. Improved the tooltip behavior:

   • Set delayDuration={0} so the tooltip appears immediately on hover
   • Added proper alignment and positioning
   • Made the tooltip button more visually distinct with padding and hover effects

4. Enhanced visual clarity:

   • Used a rounded-full background on hover to make the button more distinct
   • Improved spacing between the source name and the "+N" indicator
   • Made the tooltip button look more interactive with clear hover states

Now you should be able to hover over the "+N" indicator to see the tooltip without triggering the row selection, and the tooltip interaction should be much more reliable and intuitive.

You're right - there seems to be an issue with the tooltip not appearing. Let's fix the tooltip implementation to ensure it displays properly:

I've implemented a custom tooltip solution that should work reliably:

1. Custom tooltip implementation:

   • Instead of relying on the shadcn/ui tooltip component, I've created a custom tooltip implementation
   • The tooltip is a simple div that appears when hovering over the "+N" indicator
   • It has proper positioning, styling, and even a small arrow pointing to the trigger

2. Improved interaction:

   • The tooltip appears on both hover and click (for mobile users)
   • Added state management to track which tooltip is currently active
   • Ensured proper z-index so the tooltip appears above other elements

3. Enhanced visual design:

   • Clean white background with a subtle shadow and border
   • Proper spacing and typography
   • Small arrow pointing to the trigger for better context

4. Reliable behavior:

   • The tooltip will appear when you hover over the "+N" indicator
   • It will disappear when you move your mouse away
   • It can also be toggled by clicking (useful for touch devices)

This implementation should work reliably across browsers and devices. The tooltip will now appear when you hover over the "+N" indicator, showing you the full list of matching sources.
