It looks like this was fixed a couple years later in this commit:

commit 7ccedcb486ee4e37da54dd82a8557c80616d9467
Author:     Artur Malabarba <bruce.connor.am <at> gmail.com>

    * lisp/faces.el: Refactor common code and fix a bug
    
    (faces--attribute-at-point): New function.  Fix a bug when the
    face at point is a list of faces and the desired attribute is not
    on the first one.
    (foreground-color-at-point, background-color-at-point): Use it.

And I've verified that (foreground-color-at-point) seems to return
sensible results in the test cases in Emacs 29, so I'm closing this bug
report.
