           Summary: REGRESSION: "add" method of <select> object does not put
                    the <option> object in the correct position
           Product: WebKit
           Version: 420+ (nightly)
          Platform: Macintosh
        OS/Version: Mac OS X 10.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P1
         Component: New Bugs
        AssignedTo: webkit-unassigned at opendarwin.org
        ReportedBy: opendarwin at sebastiancelis.com


In certain circumstances, it seems as though
selectObj.add(optionObj, selectObj.options[0]);
does not actually add optionObj to the beginning of the select object.

>From my testing, it looks as if this bug only occurs if the selectObj is
created dynamically using document.createElement("select");

The first time the "add" method is called, it works fine.  On subsequent calls,
the <option> objects are placed at lower positions in the <select> list.  It is
as if selectObj.options[0] is not updated to return the correct object after
the "add" is performed.  This is confirmed by calling
alert(selectObj.options[0].value); after each call to the "add" method.

This issue is not present in WebKit 4.19.3.

I am attaching a test case reduction which demonstrates the issue.
