Using Malli for coercion. How do I set up a (query) param for a list of values conforming to a regex?

(def id-regex #"^[A-Za-z\d\-_]{10}$")

(def routes
  ["" {:coercion reitit.coercion.malli/coercion}
   ["/some-path"
    {:get {:handler    some-handler-fn
           :parameters {:query
                        [:map
                         [:some-arg
                          [:sequential
                           [:re id-regex]]]]}}}]])
The endpoint shows up in Swagger docs, but when I test it with one or more values, the endpoint throws me errors.
{
  "schema": "[:map {:closed true} [:some-arg [:sequential [:re #\"^[A-Za-z\\d\\-_]{10}$\"]]]]",
  "errors": [
    {
      "in": [
        "some-arg"
      ],
      "path": [
        "some-arg"
      ],
      "message": "invalid type",
      "type": "malli.core/invalid-type",
      "schema": "[:sequential [:re #\"^[A-Za-z\\d\\-_]{10}$\"]]",
      "value": "1234567890,1234567891"
    }
  ],
  "value": {
    "some-arg": "1234567890,1234567891"
  },
  "type": "reitit.coercion/request-coercion",
  "coercion": "malli",
  "in": [
    "request",
    "query-params"
  ],
  "humanized": {
    "some-arg": [
      "invalid type"
    ]
  }
}
Looks like it's processing the query parameter as just a string instead of a sequence of strings.
