I think the changed fontSize together with changed
StaffSymbol.staff-space, causes different behaviour of the Slur.

Why not \shape?
You can use it as tweak and for broken Slurs as well, pseudo-code:

<note> -\shape #'(
  () ;; do nothing for first part
  my-number-pair-list ;; tackle second part
)
( ;; start Slur
\break
<other-note> ) ;; end Slur
