defface does indeed run at load time, but the face copying is not a
magic wand: it can only copy into the face definitions of those frames
it finds in the value returned by (frame-list).  And the new frame is
not there yet.  Look at the code of copy-face, and you will see it.

Because faces in Emacs are frame-local by design.  Changing face
definitions on one frame doesn't propagate them to other frames,
unless some code walks the frame list and does that.  copy-face indeed
does this walking, but it cannot do it for non-existing frames.

A bad habit, I must say ;-)

You don't need to actually do it via M-x customize-face if you don't
like, simply use set-face-foreground etc. for woman-bold-face.
