What about the ones with the overflow?

I have not been able to find any instance of this.

         a.title = url;
-    else if (typeof tooltipText !== "string" || tooltipText.length)
+    else if (tooltipText)
         a.title = tooltipText;
     a.textContent = linkText.trimMiddle(WebInspector.Linkifier.MaxLengthForDisplayedURLs);
     if (isExternal)
         a.setAttribute("target", "_blank");
 
     return a;
 }
