User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.16) Gecko/20080715 Fedora/2.0.0.16-1.fc8 Firefox/2.0.0.16
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.1) Gecko/2008071615 Fedora/3.0.1-1.fc9 Firefox/3.0.1

When wrapping an anchor element around a <button> element, the linked item is fetched twice. This is not the behavior in Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.16) Gecko/20080715 Fedora/2.0.0.16-1.fc8 Firefox/2.0.0.16

I am attaching an example PHP file.


Reproducible: Always

Steps to Reproduce:
1. Click the button without the anchor element.
2. Wait for 2 seconds.
3. Click the linked button.
4. Wait for 2 seconds
5. Click the link
Actual Results:  
The first click does not reload the page. http://www.w3.org/TR/REC-html40/interact/forms.html#edef-BUTTON says the button should behave like a <input type="button"> element, so the behavior is acceptable.

The second click reloads the page and in the log file (test.txt) I get two lines with the current UNIX timestamp. I.e. the page is requested twice. Once for the outer link, and once again for the <button> tag. (probably)

The third link reloads the page and yields one new line in the log file.



Expected Results:  
The second link should only generate one request.
