Spring Cloud Gateway not allowing Encoded URL paths after Update about spring-cloud-gateway

We have the same issue - we remove one param calling:
GatewayFilterSpec.removeRequestParameter("paramName") and I found that when value of (not removed) param contains encoded value (for exmple %5B) the param is sent without encoding.
When I try to debug the problem I get into RemoveRequestParameterGatewayFilterFactory.apply method - there is line:
MultiValueMap<String, String> queryParams = new LinkedMultiValueMap(request.getQueryParams());
where queryParamsin request are encoded, but in Map queryParams there is decoded value (which is probably correct). But the params are reinserted on the line containg:
URI newUri = UriComponentsBuilder.fromUri(request.getURI()).replaceQueryParams(CollectionUtils.unmodifiableMultiValueMap(queryParams)).build().toUri();
and values are not encoded again.
