Spring Loss of context path after using ServerRequest.from

Recently I found a strange behaviour after adding a Filter to our project that uses ServerRequest.from. After I added the filter the contextPath was gone and the pathWithinApplication contained the full path.

As we are using a reverse Proxy and want to return correct location headers we are dependent on the contextPath set by the ForwardedHeaderTransformer.

My question is if this is intended behaviour or is this a bug in the framework.

I think I found the culprit of this behaviour here:

public BuiltServerHttpRequest(String id, HttpMethod method, URI uri, HttpHeaders headers,
                MultiValueMap<String, HttpCookie> cookies, Flux<DataBuffer> body) {
            this.id = id;
            this.method = method;
            this.uri = uri;
            this.path = RequestPath.parse(uri, null);
            this.headers = HttpHeaders.readOnlyHttpHeaders(headers);
            this.cookies = unmodifiableCopy(cookies);
            this.queryParams = parseQueryParams(uri);
            this.body = body;
        }

in the this.path = RequestPath.parse(uri, null); where the context path is explicitly set to null.

The issue looks similar to https://github.com/spring-projects/spring-framework/issues/25279 where the behaviour was fixed for mutating ServerHttpRequests
