Description

https://github.com/envoyproxy/envoy/pull/9633 introduced an assumption that field masks will operate on at most one Any resource at a time. A single DynamicListener, might legitimately refer to both a warming and active listener by the same name and thus require a field mask capable of indexing through two (or more) Any resources.

Contributor guide

Research direction
Examine the PR #9633 to understand the current field mask assumption. Then identify how DynamicListener resources for both warming and active listeners require index updates in the field mask logic.
