Confirmed with r63561 on Leopard. Also happens in Safari/WebKit 4.0.5.
Comment 5 Alexey Proskuryakov 2012-03-21 10:07:58 PDT
Still happens with Safari 5.1.4 and with current ToT.

Would be good to know when this regressed.
Comment 7 Alexey Proskuryakov 2012-03-21 11:36:19 PDT
This was broken in mid-2010 already, so finding a regression range would be tricky.
