See ei tööta PR kirjelduses välja reklaamitud kujul (eeldan, et pead siin silmas layouts struktuuri lõppu sorteerimist):

Additionally, if the content type doesn't exist in the given preferred_order array, sort the layout to the end of the manifest.json file.

Nt konstrueerides struktuur:

layouts = [
  {                                  
    "content_type" => "product",     
  },                                 
  {                                  
    "content_type" => "page",        
  },                                 
  {                                  
    "content_type" => "blog_article",
  },                                 
  {                                  
    "content_type" => "blog",        
  },                                 
  {                                  
    "content_type" => "ding",
  },                                 
  {                                  
    "content_type" => "dong",        
  },                                 
]                                    

on tulemus:

  "layouts": [
    {
      "content_type": "ding"
    },
    {
      "content_type": "dong"
    },
    {
      "content_type": "page"
    },
    {
      "content_type": "blog"
    },
    {
      "content_type": "blog_article"
    },
    {
      "content_type": "product"
    }
  ]

Peaks olema:

Suggested change

	(preferred_order.index(a.fetch('content_type')) <=> preferred_order.index(b.fetch('content_type'))) || 1
	type_index = ->(e) { preferred_order.index(e['content_type']) || Float::INFINITY }
	layouts.sort { |a, b| type_index[a] <=> type_index[b] }

Ühtlasi peaks see meetod private olema.
