Cdcr Bootstrapping does not cause "index copying" to follower nodes on Target

Please find the discussion on:
http://lucene.472066.n3.nabble.com/Issue-with-CDCR-bootstrapping-in-Solr-7-1-td4365258.html

If we index significant documents in to Source, stop indexing and then start CDCR; bootstrapping only copies the index to leader node of shards of the collection, and followers never receive the documents / index until and unless atleast one document is inserted again on source; which propels to target and target collection trigger index replication to followers.

This behavior needs to be addressed in proper manner, either at target collection or while bootstrapping.
