Describe the problem/error/question

When looking at execution logs of a parent/top-level workflow, the “View sub-execution” is not always available for sub-workflow nodes (even though all subworkflows ran).

These pics are from the same parent execution:

The “View sub-execution” link only shows up when the sub-workflow was executed as a separate execution (e.g., via Execute Workflow node with “Execute Workflow in a new process” enabled). If the sub-workflow runs in the same process, its details are included directly in the parent execution and the link won’t appear.
