1. Navigate to http://www.webkit.org
2. Open WebInspector
4. Open inspector on inspector
5. View properties of WebInspector.mainResource using console
6. Compare this to first entry in WebInspector.panels.network._resourcesById
EXPECTED: These two objects should refer to the same resource
ACTUAL: WebInspector.mainResource lacks all network information (start/end times, identifiers, HTTP status etc).
This is gone now that bug 61192 is fixed.
