- * It does not currently return the correct value in the case of an iframe whose
- * source URL results in a redirect because the loading of the iframe does not
- * generate a history item. This is most likely a rare case and is consistent
- * with the current behavior of the capybara-webkit driver.

- *
- * QWebFrame->requestedUrl()
- * QWebHistoryItem.url()

- * In the cases that we have access to both the QWebFrame values and the
- * correct history item for that frame, we can compare the values and determine
- * if a redirect occurred and if pushState was used. The table below describes
- * the various combinations of URL values that are possible.
- *
- *   O -> originally requested URL
- *   R -> URL after redirection
- *   P -> URL set by pushState
- *   * -> denotes the desired URL value from the frame
