I have set the option number_path to false because I thought that would control the entire display of the numbers in headings. I want to keep the decimal option for the ToC-Block but dont want the numbers displayed in the headings.
If that is the intended behavior we need another condition in the template_preprocess_toc_header hook.
Set number_type to decimal
Set number_path to false
Check the rendered headings. Nothing change if number_path is true or false
Clarify the intended behavior. Add $options['number_path'] as AND condition.
