Ability to see edit history of a test and revert specific changes in test

It would be helpful to have a visible edit history for tests, along with the ability to revert to a previous state.

A few scenarios where this would come in handy:

When Bugbug has a false failure on a run but passes a few minutes later, the current workaround I do is to duplicate a step to get it to register. Once the test is stable, those added steps need to be cleaned up manually. A revert option would make that much faster.

Accidental edits through drag-and-drop are also easy to make and hard to undo, especially if you don't catch the change right away. Edit history would make it easy to identify what changed and get back to a known good state.

Ideally, this would look something like a step-level changelog with timestamps and the ability to restore any prior version.
