Responding to flagged posts

I have a moderation question: When you select Ignore in response to a “post requires staff attention” flag, the resulting reply is highlighted with a yellow background. But selecting other actions such as Agree or Reply does not generate the same colored response. Is this by design or a bug? It seems to me the behavior should be no color in all cases unless specifically selected. Thanks.

Can you screenshot what you mean? I am unclear.

I don’t have any active flags right now, but I was referring to the staff color of the “Thanks for letting us know” messages that are generated when you choose an action.
