Don’t know if it was added after your comment, but there actually is one separate page for each character, just click the arrow in the top-right corner of each box. For more "giant" character previews I can recommend https://decodeunicode.org/en https://decodeunicode.org/en (which is more focussed on writing systems though). There is also a "Copied x" toast (is this the correct term? idk) at the bottom of the viewport when you click a character box, maybe it was also added later on.
