CWLViewer fails to render a workflow, possibly due to commas in the name

Hi,

I copied this workflow from a project at CERN (credits to them, I never worked with this, just from communication with another researchers from there): https://gitlab.cern.ch/lhcb-dpa/analysis-productions/lbapcommon/-/blob/master/tests/example_workflows/complex_workflow_with_filtering/AnaProd_example_workflows_job_tuple%2Csplit%2Cfilter_B0.cwl?ref_type=heads

As the domain is not accepted by CWLViewer, I copied it to a GitHub repo (no guarantees this link works in +1 year 😬 ): https://github.com/kinow/test-cwl/blob/master/AnaProd_example_workflows_job_tuple%2Csplit%2Cfilter_B0.cwl

Importing it, I get a blank graph.
