fontsizev3

The fontsizev3 extension (new in v4.1.2) re-defines the various font-sizing commands (like \tiny, \small, \large, etc.) to be the sizes that they were in MathJax v3 and in v4 prior to v4.1.2, when they were corrected to be consistent with the sizes used in actual LaTeX. This extension is intended for those sites that have legacy content where the old sizing values are critical to the layout.

This extension is not loaded automatically when the autoload extension is used. To load the fontsizev3 extension explicitly, add '[tex]/fontsizev3' to the load array of the loader block of your MathJax configuration, and add 'fontsizev3' to the packages array of the tex block.

window.MathJax = {
  loader: {load: ['[tex]/fontsizesv3']},
  tex: {packages: {'[+]': ['fontsizesv3']}}
};

or, use \require{fontsizesv3} in a TeX expression to load it dynamically from within the math on the page, if the require extension is loaded.
