Is adding more proof/evidence not allowed?

Question

So there's a question someone already answered, but I found that the answer can be improved by adding a few more examples. But it seems like this is not allowed...

As you can see below this image, I don't think that there is an error about this edit, it was more likely to make the answer better...

Shouldn't we do that? Keep improving the answers?

The rejection reason is:

"This edit was intended to address the author of the post and makes no sense as an edit. It should have been written as a comment or an answer."

But I did not have that intention, I was just trying to make the answer more perfect... that's it...

So is it not recommended to do edits like these?

Answer 1

I was one of the people who rejected the edit and i mostly read the title of the response in the Suggested Edit Moderation Queue which was "clearly conflicts with author's intent"

this is just me but personally i feel that unless the answer is a Community Wiki edits to answers should be limited to formatting, grammar/spelling correction and/or clarification and the only time time i feel to add new stuff to an answer is when you're quoting relevant parts from exiting links or posting something supportive to the existing information presented in the answer (ie. adding a manga page or episode screenshots).

now it does look like you were coming from a good place and it's not like the information was wrong, i just felt that it wasn't right as an edit. now i could be wrong and others who rejected it might have had different reasons but if the rejected edit was incorrect and Ero Sɘnnin did want the information in the answer they can override the rejection being the post owner.
