	// Check the difference between the default enabled tags and the allowed tags
	var disallowedTags = _.difference(disallowedTags, allowedTags);

	// Don't allow extra attributes to an element
	UniHTML.setNewAllowedAttributes(allowedAttributes, 'all_elements');
	// Purify the answer text and stripe disallowed tags
	var purified = UniHTML.purify(text, {
