Cannot read property 'display' of undefined (on math element)

Apparently <math> element does not have style attribute so when using <math> elements with Paged.js the following exception is thrown:

paged.polyfill.js:884 Uncaught (in promise) TypeError: Cannot read property 'display' of undefined
    at isContainer (paged.polyfill.js:884)
