I'm trying disable custom colors

According to official docs it's possible to do using this settings

{
  "$schema": "https://schemas.wp.org/trunk/theme.json",
  "version": 2,
  "settings": {
    "color": {
      "custom": false
    }
  }
}

But it does not works for me, Custom color picker still displays and available to setup in wordpress admin.

Step-by-step reproduction instructions

1. goto Appearance-> Editor
2. then select for example Edit for single template (or any other template)
   
3. goto Styles
   
4. goto Colors
   
5. goto Palette
   
6. Custom section still here
   

Why this is incorrect? Because if we use similar key to disable Default Colors - it will be hidden in this global settings
