Which issue does this PR close?
Closes #8403.
Rationale for this change
As described in the issue, window function RANK gives wrong results for some cases, also fails during execution for some other cases. The PR8445 resolves the wrong result generation (This PR is merged).
This PR resolves the failure problem during execution. As far as I can tell this PR and #8445 jointly solves the issue.
