This one needs explanation too.

Updated. If the url is already displayed on the page, don't show an additional
tooltip. Also the condition (typeof tooltip !== "string") is unused.
This should also be Tooltip.install but it is in bindings/

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