Examples
Stage a selected Code Action
Workflow: Discover and stage a Code Action, step 3.
Replay the selected action against its original snapshot and stage the resulting source changes.
Expected outcome: The action is replayed against the exact snapshot and its changes advance the active transaction revision.
