Comment 4 Alexey Proskuryakov 2010-07-16 12:37:43 PDT

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.
