Conditional settings (visible_if) not working on sidebar settings

[prestarocket]

Describe the bug
According to the documentation, conditional settings should work on all sidebar settings (https://shopify.dev/docs/storefronts/themes/architecture/settings#conditional-settings).
On header settings, it doesn't work at all, and on paragraph settings, it works but I get a theme check alert: ‘Property visible_if is not allowed.theme-checkValidJSON’.

  {
        "type": "checkbox",
        "id": "headings_font_advanced_settings",
        "label": "t:settings_schema.commons.apply_advanced_settings",
        "default": false,
        "info": "If you apply advanced settings, you need to set the font size for each heading"
      },
      {
        "type": "header",
        "content": "t:settings_schema.typography.h1.size_heading",
        "visible_if": "{{ settings.headings_font_advanced_settings == true }}"
      },
      {
        "type": "paragraph",
        "content": "t:settings_schema.typography.commons.info_advanced_settings_headings",
        "visible_if": "{{ settings.headings_font_advanced_settings == false }}"

      },      

Expected behaviour
Header should be hidden with visible_if

Actual behaviour
header is never hidden

Hey @prestarocket I think this should all be working now. Please let us know if you're still running into issues.

@graygilmore The issue is still present. Headers remain visible regardless of visible_if condition, while other setting types in the same block (checkbox, select, text, etc.) correctly hide/show. Per documentation, all sidebar settings (including header) should support visible_if.

It's definitely not resolved. Headers in the schema settings do not respect the visible_if value.
