'cursor' is not really a face used by the Emacs display.  It's more
like a handle to inject the 'cursor-color' parameter into a frame's
parameter alist.  And there's no code to do that when you remap the
'cursor' face, so the above has no effect.

By contrast, when you use (for example) set-face-background to change
the 'cursor' face, that function eventually calls
get_lface_attributes, which handles this face specially, see there.
