Cross-staffs where a note is already displaced

[David Wright]

I can't figure out how to make crossStaff work when one component
has been displaced by the interval of a second. I came up with a
hack (a hidden note) in example 3, but it has the side effect of
leaving the accidental (when there is one) rather far over.
Is there a better way?

Also, in particular, why is the f4 displaced in example 2,
seeing as I have shifted the <d'' g'> well out of the way?

Cheers,
David.
