No nsIWebProgressListener callbacks when clicking on a "target=_blank" link?

Hi all,

the subject says it all. I was expecting at least some activity on a
nsIWebProgressListener interface even if I do NOT implement any "new
tab/popup/new window" functionality (via nsIWindowCreator), but
nothing happens at all.

Is implementing nsIWindowCreator  (or nsIWindowCreator2, obviously)
the only way to get notifications about clicks on "target=_blank"
links??
