Formatter alignment of function closing parenthesis unexpected

consider:
```jsonnet
local myfunc(
name = 'foo',
) = {
name: name
};

myfunc()
```

jsonnetfmt converts this to:
```jsonnet
local myfunc(
name='foo',
) = {
name: name,
};

myfunc()
```

Why did it add the indentation before the close parenthesis?
