GitHub Actions Bug: ${{ github.workflow }} Context Variable Causes Child Workflow Runs to Be Prematurely Canceled

[choyshaowei]

Describe the bug
GitHub Actions ${{ github.workflow }} incorrectly returns the parent workflow's name in child workflows. This causes child workflows to be grouped under the same concurrency group as the parent, leading to unintended cancellations of child workflow runs due to perceived deadlocks.

To Reproduce
Steps to reproduce the behavior:

1. Create a parent workflow that triggers on pull requests and calls child workflows.
2. Define concurrency groups using ${{ github.workflow }}-${{ github.ref }}.
3. Trigger the workflow by opening a pull request.
4. Observe that after the first child workflow run starts, subsequent runs are canceled.

Expected behavior
Each child workflow should have its own concurrency group based on its workflow file name, allowing all child workflows to run independently without being prematurely canceled.

Runner Version and Platform

Version: GitHub Enterprise Server 3.9.10
Platform: GitHub-self-hosted runners

OS of the machine running the runner?
Linux

What's not working?

Subsequent child workflow runs are canceled, with logs indicating a deadlock in the concurrency group.
