I think the reason is that global meta bindings are looked up in the
ESC-prefix map, which is referenced in the top-level keymap using a
symbolic reference, not as an embedded keymap.
Even if copy-keymap recursively copies embedded keymaps, it does not
seem to recursively copy such symbolic references (which makes sense I
suppose).
(lookup-key (current-global-map) "\e") => ESC-prefix
