"See x new or updated topic" alert when I bulk archive messages

This feels like a bug but is fairly minor, but in recent weeks a new “See x new or updated topic” alert pops up when I use the feature to select multiple messages and archive them. I don’t think it used to do this, and it feels weird to be alerted to it all the time - I know I just archived them so you don’t need to tell me. Also, it says they are “topics” and not “messages”.
