bug#32706: 27.0.50; Gnus ignores gnus-visual nil after gnus-article-outlook-deuglify-article

[Filipp Gunbin <fgunbin@fastmail.fm>]

I have gnus-visual set to nil and articles are not fontified (correct).

But if I invoke `W Y f' (gnus-article-outlook-deuglify-article) on an
article, then it gets fontified.  It's not the only command after which
I observe such behavior.

It's not easy to reproduce this with emacs -Q, but I'd be happy to help
if you tell me how.

Thanks.
