The {productname} 7.8.0 release includes an accompanying release of the Math premium plugin.
Math includes the following addition.
To improve flexibility when working with MathML content, especially in cases where new attributes or elements are not yet supported by DOMPurify, two new configuration options have been introduced: extended_mathml_elements and extended_mathml_attributes.
Prior to 7.8.0, MathML elements and attributes could be configured informally, but were not officially supported. With enhanced security measures introduced in {productname} 7.8.0, MathML content is now filtered separately from HTML using DOMPurify, and any unsupported elements or attributes are stripped from the editor content. This change increased security but removed the ability to allow certain MathML-specific content.
The new options allow users to define lists of MathML elements and attributes that should be preserved, even if DOMPurify does not currently recognize them. This enables quicker user-side updates in response to evolving MathML specifications without disabling sanitization or waiting for upstream changes.
-
extended_mathml_elements: allows a list of additional MathML elements to be preserved. -
extended_mathml_attributes: allows a list of additional MathML attributes to be preserved.
These options apply only within MathML contexts and do not affect general HTML content. They enable use cases such as preserving <mn> elements and attributes like linebreak in MathML expressions.
tinymce.init({
selector: "textarea",
extended_mathml_elements: [ "mn" ],
extended_mathml_attributes: [ "linebreak" ]
});<p>
