Description

when "comma_first" is set to true, new lines are added between elements each time script is run. this problem occurs only in arrays, objects look fine. also, if "max_preserve_newlines" is set to 0, this wont happen. but new lines intentionally added are stripped.

Input

The code looked like this before beautification:

a = [
  1,
  2,
  3,
  4,
  5,
 ];

b = {
a: 1,
b: 2
}
  

Current Output

The code actually looked like this after beautification: (problem shows itself after second run)

a = [
  1
  
	, 2
  
	, 3
  
	, 4
  
	, 5
 ];
b = {
	a: 1
	, b: 2
}

Expected Output

The code should have looked like this after beautification:

a = [
    1
    , 2
    , 3
    , 4
    , 5
];

b = {
    a: 1
    , b: 2
}
