In r94451, when using Yahoo! Mail, clicking sidebar links, such as Inbox and Spam do not trigger the expected behavior (opening said folder). This was working for me as of 4 nighties ago. If requested I'll find out which nightly it broke in. To Reproduce: 1. Go to mail.yahoo.com 2. Login 3. When the interface loads, attempt to click the Inbox in the left sidebar
Regression range r94444-r94448, meaning that it's http://trac.webkit.org/projects/webkit/changeset/94445 (Use bump allocator for initial property storage).
That patch has been rolled out in http://trac.webkit.org/changeset/94522, so the problem should be fixed in current nightly.
