Allow Background Color in Mails

Hi there, I found this Issue Allow font colors in articles (not only in tables) · Issue #3345 · zammad/zammad · GitHub regarding the sanitizer allowing style="color:red" in the ticket view.
Many people at our company use the highlight function of outlook which sets style="background:yellow".

So I wondered if it is possible to allow background color like the font color.
I understand this might cause UI problems with the whole background but maybe you guys have some ideas if there might be a feasible solution

Kind regards
Thorben
