I wonder when the regression was introduced. Maybe this could help to
pin down the problem and give a hint at the proper fix. I cc'ed Stefan,
since he can judge better if the proposed fix is good. I would at least
add a comment, explaining why the properties are copied.

Eli, are you okay with adding a fix for this problem to emacs-29? The
pcomplete help functionality is new functionality introduced in Emacs
29, but it never worked properly, it seems.

Daniel
