Once the user is on the edit summary screen, we want to record these actions:
- Impression for the screen, including whether they accepted or rejected the image (this indicates the state of the screen).
- Selecting the "back" arrow to return to the caption step.
- Selecting the "review your changes" button.
- Selecting the Publish/Submit button.
- If the user had accepted the image, the publish event should include the number of characters in the caption.
