The workflow for reviewing your changes (diff) to type in the edit summary is annoying.

Scenario:

1. Make changes to the page
2. Click "Publish changes…" to save them
3. Faced with the "Edit summary" field, click "Review my changes" to remind yourself what you did
4. Click the back button in the top-left corner to go back to editing the edit summary

See, I pulled a fast one on ya! The back button is not actually in the top-left corner like it always is, it's instead in the bottom-left corner! The button in the top-left corner that you just clicked will close the entire dialog. (You scoff at yourself and look for the "Publish changes…" button again.)

Replacing the verbose labels with close/back icons (T225021) would help a little. But I think we should actually just replace the current top-left button with the bottom-left button, so that clicking there goes back. To close the dialog entirely, you just click twice.

Alternatively, we could keep the edit summary field visible while reviewing changes (T148297), but that's a bit more involved.
