Multiple grace notes: not enough space allowed between notes

MS 3.

See attached file.

When a single acciaccatura is applied before a note there appears to be sufficient space (?) but when two or more grace notes are applied the spacing is too tight. This requires not just adjustment of the Chord X offset(s) for the grace notes but also the leading space for the parent note.

Is there room for improvement here? Perhaps a style property that applies a minimum spacing to multiple grace notes?
