{
            "1234567891234567891234567891234": -4
}

Expected Output

The code should have looked like this after beautification:

{
            "1234567891234567891234567891234": -4
}

Actual Output

The code actually looked like this after beautification:

{
            "1234567891234567891234567891234": -
            4
}

Steps to Reproduce

        options = jsbeautifier.default_options()
        options.indent_size = 4
        options.brace_style = "expand"
        options.wrap_line_length = 40
        obj = {
            "1234567891234567891234567891234": -4
        }
        json.loads(jsbeautifier.beautify(json.dumps(obj), options))
