hyperlink box in posts editor needs to be widened

So when writing up posts with the guttenburg editor, whenever I need to link some text so say another post or product, it’s becoming a nuisance that the box isn’t wide enough and not showing the full url and title in the preview to select from. There’s several products that all start with the same but just have a different ending. If it were just a bit wider so I can see the full url or title would be great. The old editor was fine with this.
