I can verify this on Ubuntu 24.04.4. I did a git bisect and found
the difference (bug?) to have been introduced at patch 9.2.0192.
This behavior is not affected by "k" in 'cpoptions'. I haven't
looked into it further.

patch 9.2.0192: not correctly recognizing raw key codes

Problem: When "k" is excluded from cpoptions, vim should be able to
recognize raw key codes in mappings and replace them with
builtin codes (e.g. ^[OA is replaced with <Up>) so that
changing the builtin code also changes the mapping to match.
Currently, this only works properly if the builtin code does
not contain modifiers (e.g. @;*).
Solution: Teach find_term_bykeys how to recognize keys with modifiers
(AstroSnail).

fixes: #19182
closes: #19643
