`consistent-list-newline` has inconsistent behavior when single or multiple properties in an object ?

Describe the bug

In an object with a single property :

// The following ...

export const object = { a:1
}

// ... gets fixed to 

export const object = { a: 1,
}

In an object with multiple properties :

// The following ...

export const object = { a: 1, b:2
}

// ... gets fixed to 

export const object = { a: 1, b: 2 }

I would expect that when starting writing properties inline, both brackets stays inline (as it is the case for object with multiline properties in the example above). What is supposed to be the correct behavior ? Can it be configured so that it mimics the behavior of object-curly-newline with consistent: true ?
