           Summary: decidePolicyForNavigationAction not called for
                    subsequent clicks on fragment anchors
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh
               URL: http://www.w3.org/TR/html401/index/list.html
        OS/Version: Mac OS X 10.5
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: WebKit API
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: opendarwin at lapcatsoftware.com


Overview Description:
Some anchors consist entirely of fragments, e.g., <a href="#m">M</a>. The first
time you click on such an anchor, the <WebPolicyDelegate> method
-(void)webView:(WebView *)sender decidePolicyForNavigationAction:(NSDictionary
*)actionInformation request:(NSURLRequest *)request frame:(WebFrame *)frame
decisionListener:(id<WebPolicyDecisionListener>)listener is called. However,
the method is not called on subsequent clicks on the anchor.

Steps to Reproduce:
1) Unzip, open, build, and run attached sample Xcode project
DecidePolicyFragments.
2) Enter the URL http://www.w3.org/TR/html401/index/list.html in the text field
and press return.
3) After the webview is loaded, click in the webview to give it focus.
4) Click on the "M" link at the top of the page.
5) Scroll back up to the top of the document.
6) Click the "M" link again.

Actual Results:
decidePolicyForNavigationAction is not called

Expected Results:
decidePolicyForNavigationAction should be called

Build Date & Platform:
Build 2008-09-14 04:33:37 -0500 (Sun, 14 Sep 2008), WebKit svn revision 36403

Additional Builds and Platforms:
Mac OS X 10.5.4 Build 9E17, Mac OS X 10.4.11 Build 8S2167

Additional Information:
If you click "M", click a different link such as "N", and then click "M" again,
decidePolicyForNavigationAction does get called. The bug only occurs if you
click the same link multiple times in a row. This problem is reproducible with
any fragment anchor.
