Redirect loop with "Enforce clean and canonical URLs"

Have site where lot of parts are made of Angular. For that reason, it was required to use trailing slash before parameter. Like
/search/?query=potato after "/search". This trailing slash is added in code that makes redirect afterward:

if (strpos($request->getUri(), '/search/') === FALSE) {
  // Make sure we load the page with a trailing slash, otherwise the angular app has issues.
  $url = preg_replace('/\/search/', '/search/', $request->getUri());
  return new RedirectResponse($url);
}

but then redirect module redirects it again without trailing slash (/search?query=potato), so it makes a redirect loop.

Not an expert in Angular - something could probably be changed so it works, but in general - this could be also not angular need. Maybe some "exception paths" field be added, so this could be configurable? Currently, the only option was to opt-out "Enforce clean and canonical URLs" checkbox. Other ideas how to pass this redirect so it respects custom modules needs?
