Actually, the first suggested edit in all likelihood did not change the title to all caps. It was already in all caps in the original post, and the suggested edit merely failed to fix it. Check the timeline:
This seems to be a bug: the suggested edit was accepted for submission even though the post had been edited since the original version. Since all of this happened in the first 5 minutes of the post, it's possible that a non-recorded edit by the original poster muddied matters further.
Suggested edit diffs are wonky when there are concurrent edits, you can't set store by them.
For the second suggested edit, the timeline is:
The first suggested edit retained the
> marks left over from the quotation formatting in the original, presumably because Monica had started editing from the original and not from the result of edit #1. Leaving the
> marks was an error, and could have been a valid rejection reason, however the suggestion was not the vandalism that it looks like at first glance. Again, the suggested edit should have been rejected by the system due to another edit having taken place.
As for removing
import statements, it has been suggested but turned down. This would be a valid reason to reject with a custom message.
