Allow empty workspace

Is there a way to have Opera open without having open tabs? "Allow
Empty Workspace" in the Opera Preferences Editor should make that
happen, but alas it does not. When you open Opera there is a blank
tab, when you close the blank tab Opera will close. In my eyes highly
annoying.

Thanks.
