With this suggested edit, the review page doesn't show the correct question body with the original suggested edit; the question body shown is the last revision of the post instead. The suggestion only shows the title change suggested:
That is evident from the revision page.
Note that the body was edited by me after I clicked the 'improve' button, the suggested edit page now shows the body as revised by me instead of what was there before my revision.
I improved the edit because it was clear the body needed improving too, but if now somebody looks at the suggested edit page, they could wonder why the edit was rejected via the 'improve' button, when the only possible edit was changing the first letter in the title.
The same doesn't happen for this suggested edit, though.
