In Gmsh the rule is that "if you want the n-th dimensional mesh to be
constrained by the (n-1)-th dimensional one, all (n-1)-th dimensional
entities have to be connected to n-th dimensional ones".

In your example this means that the surface has to be connected to a
volume (see attached file).

You have the same phenomenon if you define

- a curve in the middle of the volume: the line elements on the curve
will be forced to be edges of tetrahedra in the final 3D mesh only if
the curve is connected to a surface, itself connected to a volume;

- a point in the middle of the volume: the single node discretizing this
point will be forced to be a vertex of one of the tetrahedra in the
final 3D mesh only if this point is connected to a curve, itself
connected to a surface, itself connected to a volume...

Hope this helps,

Christophe
