The main reason is that it's painful to do it in `input-decode-map`
because it has to be done not just for `mouse-4/5/6/7` but for all
combinations of possible modifiers (shift, control, alt, meta, super,
hyper, double, triple, down), so that's like a couple thousand entries
we'd need to put in that map.

                keymaps which can compute the binding for a given key)"
