it gets tricky...in this case the extension is literally just deleting the posts from the DOM (local copy of html stored in your browser), it's not replacing what it deletes with 'fresh' content from the blockchain that passes the filter, in this case, that isn't a resteem. In order to do that, we have to add a couple big layers of complexity on top...BUT...I think it's doable.
