Redactor removes article tag from HTML while saving I'm using Craft 3.x. I'm using the Redactor plugin in Craft. I have an HTML with an article tag (HTML tag). As soon as I save it, Redactor strips the article tag because of which UI goes for toss.

After saving, It simply removes these tags and keeps the inner tags.
You can specify custom HTML Purifier configs so that it will allow article tags and the Redactor fields will respect the configs.
