🎩 What? Why?

The preview mailer continues showing some styles rules due to something is removing style tag.
In PR #6876 there was an adapter that avoid that in the premailer process. But also, there was a custom sanitize process on the image_text_cta cell that removes it. With this PR I widen the rules adding style tag to avoid the deletion.
