Description

User reported a use case which were working before 9 but not anymore. 

The point is to logically replace a field (hereby it's id but it might behave same for any other)

fl=old_id:id,id:new_id

I'd say it's a kind of $mv new_id id. I've made a simple reproducer.

it fails with 

 - org.apache.solr.cloud.TestCloudPseudoReturnFields.test_mv_fl (:solr:core) 
[7597|https://github.com/apache/solr/actions/runs/4276380498/jobs/7444431149#step:4:7598] Test output: /tmp/src/solr/solr/core/build/test-results/test/outputs/OUTPUT-org.apache.solr.cloud.TestCloudPseudoReturnFields.txt 
[7598|https://github.com/apache/solr/actions/runs/4276380498/jobs/7444431149#step:4:7599] Reproduce with: gradlew :solr:core:test --tests "org.apache.solr.cloud.TestCloudPseudoReturnFields.test_mv_fl" -Ptests.jvms=96 "-Ptests.jvmargs=-XX:TieredStopAtLevel=1 -XX:+UseParallelGC -XX:ActiveProcessorCount=1 -XX:ReservedCodeCacheSize=120m" -Ptests.seed=4CCEBE424880B511 -Ptests.file.encoding=US-ASCII

. Then I applied it to revision preceding SOLR-9376 and test passed.  For me it seems like:

 - Solr behaved like described before, but it does not after SOLR-9376.  

 - Should we reproduce this behavior or we can suggest a workaround?
