Live preview for register_settings_form() 2

This exact topic has been asked 4 years ago here by @davidlab . I was wondering if it’s been implemented yet as I’m trying to work on having live previews in forms.

Is it possible to have a live preview for settings created within the register_settings_form() method? I tried but the settings only become active once the form is saved.

I am not sure if they ever did fix this. At the time I just went ahead and developed my own custom live preview for the form.
Sorry I don’t have any update on this.
