Message:

Formatting: Treat math elements as block-level elements.

The math element can be displayed either as a block or inline element. If wpautop only treats it as an inline element, it will break multiline elements by inserting br elements. Treating the element as a block element means that the editor won't break common normative usages of the math element.

Prevent math elements from having internal elements split up with br elements, disrupting formatting.

Fixes #13340.
