I don't think this ever worked as you expect.  I checked as far back
as Emacs 21.4, and they all behave like you describe.

The following does behave as you describe:

  . emacs -Q
  . type into the *scratch* buffer "exec-path" (without the quotes)
  . move after the 'h' in "exec-path" and type "C-j"

In the result, you can type RET or click mouse-2 on the ellipsis, and
it will behave as you expect.  But 'pp' doesn't, and seems like it
never did.  You will see in pp.el that it does nothing special to make
the ellipsis be sensitive to clicks or other keys.

I suspect that your memories are about the recipe I show above, not
about 'pp'.
