Hi Werner,

This appears to be the same issue affecting the piano centred dynamics
template when there's a system with no dynamics.

If I understand what's going on in, the
minimum-Y-extent is only added to this VerticalAxisGroup's skyline
pair if it has an X-extent. Obviously, in the case of the first
system, there are no lyrics, so it has no X-extent. Setting
minimum-X-extent to a value greater than '(0 . 0) gets around this

But it's not an engraver property; it's a grob property. I agree it
shouldn't be affecting the Lyrics context if you've removed hara-kiri,
but the setting is left over from as part of the
initialization of Lyrics.

The defaults are `not-set', which is equivalent to #f since both
properties are read using to_boolean ().
