*
* Requirements for Android Firefox to apply the system font size to a text inside an iframe:
* - The iframe document must have a header: ``.
* The only way to set it is to use the `srcdoc` attribute of the iframe;
* - The iframe content must get loaded before adding extra content with JavaScript;
