With subr.el (source), the bug59793-yank function overrides
'insert-for-yank' successfully.
With subr.elc (compiled byte-code), the function can't override
'insert-for-yank'. Just try to replace the 'cl-letf' (not 'cl-letf*')
form with an 'error' call, bug59793-yank still just inserts text, which
is, obviously, unexpected.

Both source and compiled Emacs Lisp code should show the same behavior,
except performance. But 'subr.el' and 'subr.elc' show different
behaviors. Isn't this a byte-compiler bug?
