For others looking for a solution, I found it is caused by the browser, so it has nothing to do with this module.
You can do the following to have a similiar functionality:
$form['your_field']['widget']['#options_attributes']['option_id'] = ['onclick' => 'this.checked=!this.checked;'];
It was the easiest fix I found here https://stackoverflow.com/a/155349
