@mairanteodoro would you also add the webbpsf markers to these tests? They're causing failures in stpipe: https://github.com/spacetelescope/stpipe/actions/runs/9445531594/job/26013349354#step:10:3493

Would you run this with the GA regtests (which will trigger sonar scan) to check that there's no other issues? @zacharyburnett put together some great documentation on this: https://github.com/spacetelescope/RegressionTests/blob/main/docs/run_regression_tests.md and should be able to set you up with permissions (if you don't see the 'Run Workflow' button).

Thanks for the suggestion, Brett! I will take a look into it.
