I am posting one minor change request.

Also, as we discussed, please post on this PR the regression test html output obtained by including the "test_reports" role in the list of test roles provided in the "tests/regression/test.yaml" file that you use for running the regression test. (Please "print" it in "landscape" mode to create the PDF file to be attached to the PR, scaled so the output all fits on the page.)
