I can't reproduce it.  As expected, with emacs -Q, the lambda function
never gets called.

So, I see the same on the 3 builds I've tried (GTK3, Lucid,
PGTK): Emacs starts with the default theme.

If I start with emacs -Q and then evaluate the forms inside the
lambda function, I can't reproduce it either, because I see the exact
same thing on the 3 builds: adwaita theme gets loaded and enabled, but
the font-lock-comment-face customization doesn't get customized to
yellow.

IOW, I can reproduce, but it's not pgtk specific.


I think this is related to Bug#76685.  But since I can't reproduce the
bug exactly as reported, I would like to check before merging the bugs.
