Incorrect config schema

Problem/Motivation

When checking the config schema of views using that display, one gets error reports:

The contents of

  default:
    display_options:
      style:
        type: slideshow
        options:

            advanced_options_choices: '0'
            advanced_options_entry: ''
            advanced_options: '{}'

Are included in the view, although the config schema does not describe them.
