Can you please show a reproducible recipe, starting from "emacs -Q",
that exhibits the problem you are describing? I don't think I
understand what exactly doesn't work in your case.
Also, please use "M-x report-emacs-bug" to post the details, as that
command collects important details about the Emacs build configuration
that make investigation easier.
Thanks.
