this looks quite unfortunate, how do we get a NaN here? is this because we
merged switch cases in TimelineUIUtils? If so, I'd rather have separate cases.

Done.

linkifyLocation() calls linkifier.linkifyScriptLocation with "lineNumber - 1"
which is NaN because lineNumber is undefined.

         linkText += ":" + (lineNumber + 1);
     var anchor = WebInspector.linkifyURLAsNode(url, linkText, classes, false, tooltipText);
     anchor.lineNumber = lineNumber;
