🐛 Bug

Unit test Tester.test_draw_boxes is failing on all test CircleCI builds.

To Reproduce

Steps to reproduce the behavior:

1. Make a PR that is not changing source code
2. View unit test CircleCI build results.

Sample builds that is not modifying existing source code:

• PR Added CodeQL and Bandit security checks as GitHub Actions #3625: Windows CPU Py 3.8 unit test build, Linux CPU Py 3.7 unit test build
• PR Documentation improvements for ops #3634: MacOS CPU Py 3.9 unit test build, Linux CPU Py 3.6 unit test build
