pull_request.labeled events sometimes missing from PR check summary view

I'm attempting to create a workflow that runs once in each of these cases:

• opening a PR containing a label
• adding a label to an existing PR
• pushing to a PR that contains a label

In many cases, when opening a PR containing the label in question, the action created from the pull_request.labeled event in the workflow runs but does not show its status in the mergeability details view that lists all checks.

Here are a few examples:

With concurrency

Workflow: https://github.com/urcomputeringpal/actions-bug-repros/blob/main/.github/workflows/pr-labels.yml

To accomplish the required concurrency limiting and not run the action twice when opening a PR that contains the appropriate label at creation time, I'm using the following workflow concurrency settings:

concurrency:
    group: ${{ github.workflow }}-${{ github.event_name }}-${{ github.ref }}

Affected PR: #2

In the above PR, you can see that a comment was made but no Action status is present in the mergeability detail view. Please note that this PR was run before the README.md conflicts existed.

Without concurrency

To rule out any impact of the concurrency key on this behavior, I duplicated the workflow without the concurrency limiting settings:

Workflow: https://github.com/urcomputeringpal/actions-bug-repros/blob/main/.github/workflows/pr-labels-no-concurrency.yml

Affected PR: #2

In the above PR, you can see that two comments were made but only one Actions status is present in the mergeability detail view below. Why are the checks created by the pull_request.labeled events not being associated with the PR? Please note that this PR was run before the README.md conflicts existed.

Labels added after initial PR open

The following PR demonstrates that I can't reproduce this behavior at any time other than when adding the label before creation of the PR:
