Be more exact: where did that happen? On the feed detail
pane we do not allow any "critical" content/scripting: we only
allow frames and images - no javascript,java,activeX,etc.

On all other "normal" browser tabs you can configure the
security by yourself: select Options|Web Browser. If you
check on "Javascript execution", that lines should work (and
open a new Tab, not a new window).

That is by design/for security reasons.
