Again vertical spacing FiguredBass / Staff / Lyrics

[Michael Käppler]

> I'm not top-posting
Hi all,
I'd like to clarify my former question from a few days ago:
How can I increase the minimal distance between a FiguredBass line and the
staff above? (Example attached)
It works if there are no Lyrics attached to upper staff. Otherwise the padding 
goes away for a reason I don't understand, because surely I want to keep the 
padding despite of Lyrics between.

Regards,
Michael
