Deployment checks (manual QA)

Quick QA checks that should be manually applied before deploying code to QA and Staging:

Significant changes made to QA:

1. navigate to QA: https://matheditor-QA.diagramcenter.org/
2. select a problem from the page (e.g., problem #2)
3. in the "my work" section, modify the math text box by adding in a fraction equation and your keyboard; type an annotation, then select "add step"
4. in the "my work" section again for the next step, make sure the cross out/replace/calc functions all work, add a dictated annotation, then select "add step"
5. select "add step" again (without making any changes)
6. then use the trashcan to delete the last step in the history section, then try to "undo" to bring back the deleted step
7. once the above is confirmed and working, notify the rest of the core team by email about the deployment
8. someone else (not the person who just checked in code) runs through steps 1-6 above, validating changes and reporting any new bugs that may have emerged
9. If needed, request deployment to Staging (https://matheditor-staging.diagramcenter.org/) only after a second person has validated the code in QA

note: the entire sequence of steps 1-8 should be completed before another round of code is checked in
