schema doesn't check for misspelt/new fields within array of objects

[ablewalmsley]

I noticed a bug for array of objects in JSON schemas, if I accidentally misspell a property, or add a property that is not yet in the schema to my item, it will still pass validation i.e.

{
   "type":"object",
   "properties":{
      "contacts":{
         "type":"array",
         "items":{
            "type":"object",
            "properties":{
               "title":{
                  "type":"string"
               },
               "name":{
                  "type":"string"
               },
               "phone":{
                  "type":"string"
               },
               "email":{
                  "type":"string"
               }
            }
         }
      }
   }

it will validate contacts is there and not misspelt, but if I accidentally put "telephone" instead of "phone" (or a similar mistake), within the array of objects, it will be considered valid.

Please let me know if this is intended, or if there is an available workaround.

nevermind, looks like thats a schema issue, I can just add "additionalProperties": False to fix that
