Repair - Rebuild Maven repository metadata (maven-metadata.xml) task with GA restrictions does not work

Boot up the attached work directory. Observe that it has a maven-metadata.xml file in it with a version which does not exist in repository storage:

<?xml version="1.0" encoding="UTF-8"?>
<metadata>
  <groupId>org.foo.bar</groupId>
  <artifactId>project</artifactId>
  <versioning>
    <latest>1.2.7</latest>
    <release>1.2.8</release>
    <versions>
      <version>1.2.6</version>
      <version>1.2.7</version>
      <version>1.2.8</version>
    </versions>
    <lastUpdated>20200122203438</lastUpdated>
  </versioning>
</metadata>

 The reason the file is in this state is that I deployed version 1.2.8, and then removed all of its assets via the "DELETE /v1/assets/{id}" REST API.

Now go to "system --> tasks", and see that there is a rebuild maven metadata task configured to rebuild against coordinates org.foo.bar:project . Run this task.

The maven-metadata.xml file is not updated.

Remove the group ID and artifact ID from the task's configuration. Run the task again.

The maven-metadata.xml file is updated.

Expected: Running a rebuild metadata task against a GA should rebuild the maven-metadata.xml files if they need to be rebuilt.
