Revert blocked issues from Code Review and notify assignee

Your Code Review moves can proceed with unmerged dependents, causing incomplete reviews and release delays. Revert those moves and notify assignees so reviews have full context before the next release.

Overview

When issues land in Code Review while dependent work is still unmerged, reviewers lack context and releases stall. This flow reverts those moves, adds an explanatory comment, and notifies the assignee so reviews are accurate and releases stay on schedule before the next release.
