I noticed your PR description contains closing keywords ("Resolves", "Closes", or "Fixes") referencing a "Tracking Issue".
Why this matters: Tracking issues should typically remain open until all related sub-issues are completed. GitHub automatically closes issues with such closing keywords when the PR is merged. For more information, see GitHub's documentation on using keywords in issues and pull requests.
Required action: Use "Progresses" instead to reference the tracking issue without automatically closing it.
