Spring Issue with Forwarded Header and Multiple Values

According to the RFC7239 specification, syntax for Forwarded Header is as follows: Forwarded: by=<identifier>;for=<identifier>;host=<host>;proto=<http|https>

This values are used by Spring (all recent versions), if present, in order to reflect the client-originated protocol and address (when allowed through a configuration). There is a problem when using multiple values in this header:

# Multiple values can be appended using a comma
Forwarded: for=192.0.2.43,for=198.51.100.17;proto=https;host=xxx.yyy.com;by=10.97.9.10

The code in UriComponentsBuilder#adaptFromForwardedHeaders:798-800 is getting the first Forwarded Header, if multiple are found, split it by comma and use only the first part: https://github.com/spring-projects/spring-framework/blob/a4dc13a0435484d5704e72a94a4e41c690afb381/spring-web/src/main/java/org/springframework/web/util/UriComponentsBuilder.java#L800

In our case we have result value - Forwarded: for=192.0.2.43 where all useful information is trimmed. Is this really an issue or there is something that I am missing?
