            Bug ID: 167065
           Summary: Document title changed twice when setting
                    document.title
    Classification: Unclassified
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebCore Misc.
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: mcatanzaro at igalia.com

Consider the following code:

<script>
    document.title = 'one';
    document.title = 'two';
    document.title = 'three';
</script>

In trunk, this changes the title six times: first to null, then to 'one', then to null again, then to 'two', then to null yet again. I presume that the changes to null are undesired. See bug #165073 comment 15 for a detailed description of why this happens.
