           Summary: window.opener.location can't be set in beforeunload
                    handler
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: P2

Setting the window.opener.location object (or its href property) doesn't work when performed inside an onbeforeunload event handler. Calling opener.location.reload() works, as does inspecting opener.location or opener.location.href. Setting the object or its href property works during normal page action (i.e., non-page-dismissal event) as well as during the onunload event. It's just during beforeunload that setting doesn't work.

Here's a simple test case:

<!-- main.html -->
<a href="#" onclick="window.open('popup.html')">popup</a>

<!-- popup.html -->
<script>onbeforeunload = function() { opener.location += "?foo" }</script>
