Array query parameters wrapped in anyOf do not work for single element queries

[Arskah]

If array query parameter is wrapped inside anyOf, it does not behave similar to non-wrapped parameter when querying for single elements.

  "paths": {
    "/users": {
      "get": {
        "parameters": [
          {
            "name": "id",
            "in": "query",
            "required": false,
            "schema": {
              "anyOf": [
                {
                  "type": "array",
                  "uniqueItems": true,
                  "items": {
                    "type": "string"
                  },
                  "minItems": 1,
                  "maxItems": 500,
                  "title": "Id"
                }
              ]
            }
          }
        ],
...

Current Behavior

Querying a single element throws UNPROCESSABLE_ENTITY

{
  "type": "https://stoplight.io/prism/errors#UNPROCESSABLE_ENTITY",
  "title": "Invalid request",
  "status": 422,
  "detail": "Your request is not valid and no HTTP validation response was found in the spec, so Prism is generating this error for you.",
  "validation": [
    {
      "location": [
        "query",
        "id"
      ],
      "severity": "Error",
      "code": "type",
      "message": "Request query parameter id must be array"
    },
    {
      "location": [
        "query",
        "id"
      ],
      "severity": "Error",
      "code": "anyOf",
      "message": "Request query parameter id must match a schema in anyOf"
    }
  ]
}

Expected Behavior

?id=1 should validate as an array, similar to unwrapped array.

Possible Workaround/Solution

One can query single array element with ?id[]=1 format.
