Inconsistent formatting with Javascript and brackets

[EricG-Personal]

Prettier 2.6.1
Playground link

--parser babel
--print-width 120
--tab-width 4
--use-tabs
--single-quote
--no-bracket-spacing
--trailing-comma none

Input:

let a = [{a: 'a longer string', b: 'an even longer string'}];

let a = [{a: 'a longer string', 
          b: 'an even longer string'}];
          
let a = [{
    a: 'a longer string', 
    b: 'an even longer string'
}];
        
let a = [
    {
        a: 'a longer string', 
        b: 'an even longer string'
    }
]; 

Output:

let a = [{a: 'a longer string', b: 'an even longer string'}];

let a = [{a: 'a longer string', b: 'an even longer string'}];

let a = [
	{
		a: 'a longer string',
		b: 'an even longer string'
	}
];

let a = [
	{
		a: 'a longer string',
		b: 'an even longer string'
	}
];

Expected behavior:

I would expect Prettier's opinion on how this object to look to be consistent regardless of how the user initially typed it. At the moment, there are (at least) two possible answers for how Prettier will format the same code.
