> The minimum amount settings to reproduce the bug was:

> (setq gnus-select-method '(nntp "Gmane" (nntp-address "news.gmane.io")))
> (setq gnus-treat-highlight-citation 'last)
> #+end_src
> 
> I tried to use other settings with this variable

> 1. ~(setq gnus-treat-highlight-citation 'first)~
> - The first part, HTML part is treated but the
> text part isn't.
> - With ~(setopt mm-discouraged-alternatives '("text/html"))~ the text part is treated, everything work as it should it seems.
> 2. ~(setq gnus-threat-highlight-citation 10000)~
> 
> 
> The Gnus manual states that the valid values are only:
> ~t~ or ~integer~:
> #+begin_quote
> ‘gnus-treat-highlight-citation (t, integer)’
> #+end_quote
> 
> Which means that even thou ~'first~ works it isn't intended.

> The message I used to verify the bug was,

> 2. Setting ~(setopt mm-discouraged-alternatives '("text/html"))~
>    kinda changed things even with emacs -Q,
>    some parts of the HTML part of the message looked fine while others don't.
>    The quoting fontification of the HTML isn't applied but the text part's

Eric and Andrew, any comments or suggestions?
