Trying to open a subworkflow sometimes fails.

[SolomonShorser-OICR]

For some workflows, trying to open a subworkflow fails when double-clicking in the diagram.

Description

For certain worfklows, when I try to view the subworkflow, I get an error page with the message: "Error: The workflow could not be found within the repository"

Expected Behavior

I expect a rendering of the underlying tool/workflow.

Actual Behavior

I get an error page with the message: "Error: The workflow could not be found within the repository"

Steps to Reproduce

1. go to https://view.commonwl.org/workflows/github.com/ICGC-TCGA-PanCancer/OxoG-Dockstore-Tools/blob/develop/annotator_sub_wf.cwl
2. Double-click on the step that calls the subworkflow named "level_0"
3. You will get the message: "Error: The workflow could not be found within the repository"

This also happens for the "qa_check" subworkflow.

1. got to https://view.commonwl.org/workflows/github.com/ICGC-TCGA-PanCancer/OxoG-Dockstore-Tools/blob/develop/oxog_varbam_annotate_wf.cwl
2. double-click "qa_check"
3. Get error message.

Interesting to note is that the qa_check workflow renders if you load it separately:

Context

Trying to show diagrams to new users who are using the workflow and trying to use the diagrams to help understand it.
