ds( doesn't just delete the parentheses

[CervEdin]

Given the following text

constraint
forall (c in C)
( let {}
  in ( ( bbrc: c_bbrc[c])
       in ZYX
     )
);

and placing the cursor on the 2nd opening parenthesis

  in ( ( bbrc: c_bbrc[c])
     ^

and typing ds( results in the following

constraint
forall (c in C)
( bbrc: c_bbrc[c])
       in ZYX;

in Vim surround 3d188ed in Vim 9.1

Happy to include more information if needed
