How to access Query-replace history in replace format (for eg: "ABC → XYZ")

Question

I have enabled query replace save history as below. When I am in query-replace mode, I see previous search-replace patterns of the current session in the form "ABC -> XYZ". But the search-replace patterns from previous emacs sessions dont show up as "LMN -> PQR" instead they show up as LMN for search pattern and then I need to again search for PQR as replace pattern. Is there a way to improve this?

The history of query-replace replacement pairs can be saved by adding query-replace-defaults (and also optionally query-replace-history) to savehist-additional-variables.
