Agda Auto fails for multiline code

[CSchank]

When a multiline thing is generated using C-c C-a, newlines are printed instead of used as newlines:

_ : Normal (twoᶜ {∅})
_ = ƛ\n(ƛ\n (′\n  (` count (toWitness Agda.Builtin.Unit.tt)) ·\n  (′\n   (` count (toWitness Agda.Builtin.Unit.tt)) ·\n   (′ (` count (toWitness Agda.Builtin.Unit.tt))))))

Sorry, can you provide a complete Agda file for reproduction?

I tried to reproduce this issue with the following file:

module Issue201 where

data N : Set where 
    S : N -> N
    Z : N

data Vec (A : Set) : N -> Set where
    [] : Vec A Z
    _::::::::::::::::::::::::::::::::::::::::::::::::::::::::::_ : {n : N} -> A -> Vec A n -> Vec A (S n)

example : Vec N (S (S (S (S (S (S (S (S (S Z)))))))))
example = {!   !}

I'd expect C-c C-a on the hole for example to give me a multiline result, and it did, with expected result:

example : Vec N (S (S (S (S (S (S (S (S (S Z)))))))))
example = Z ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
  (Z ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
   (Z ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
    (Z ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
     (Z ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
      (Z ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
       (Z ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
        (Z ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
         (Z ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
          []))))))))

The example above was generated with Agda-2.6.4, tried to ask Agda-2.7.0 to generate a solution but the new solver cannot find a solution somehow :|
