What is the current behavior?

A good example of is when you have long ternary like so:

func _handle_look_input():
	var input_dir := (
		Input.get_vector(&"look_left", &"look_right", &"look_up", &"look_down")
		if _can_move()
		else Vector2.ZERO
	)

This will currently ignore the newline before the if and be turned into:

func _handle_look_input():
	var input_dir := (
		Input.get_vector(&"look_left", &"look_right", &"look_up", &"look_down") if _can_move()
		else Vector2.ZERO
	)

What is the new behavior?

Now, the newline inside of the parenthesis will be preserved.

func _handle_look_input():
	var input_dir := (
		Input.get_vector(&"look_left", &"look_right", &"look_up", &"look_down")
		if _can_move()
		else Vector2.ZERO
	)
