Response-validation fails when using $ref for responses

[localh0rst]

When using $ref in the response for i.e. a get request, the response is not validated. POC:

#!/usr/bin/env perl
use v5.24;
use warnings;
use Mojolicious::Lite -signatures;

get "/test" => sub ($c) {
   $c->openapi->valid_input or return;
   $c->render(
      status  => 200,
      # Should be invalid because prop2 is missing?
      openapi => {prop1 => 200, different => 'WTF'}
   );

  },
  'test';

plugin OpenAPI => {url => "data:///spec.yaml"};
app->start;

      content:
        application/json:
          schema:
