Could you please test with an unpatched Emacs? I suspect the problem
may be difficult to reproduce there because the menus are harder to
reach from the keyboard. Or are you using the mouse?

In any case please try to reproduce it with an unpatched Emacs and
send a bug report.

According to the elisp manual purecopy does not do anything except
when building and dumping Emacs so it should not be the problem here,
