        $docx = new CreateDocx();
        $docx->embedHTML($html, ['useHTMLExtended' => true]);
        $docx->createDocx('output');

The bug is line 6436 of CreateDocx.php:

The str_replace for PHPDOCX_HTML_EQUATION_1 is also matching PHPDOCX_HTML_EQUATION11 and PHPDOCX_HTML_EQUAITON12 and so on. 

I fixed it by adding a non-numerical suffix to the key, so that the searched for string is now "PHPDOCX_HTML_EQUATION_1_".

Lines 6267/8:

$html = str_replace($equation, 'PHPDOCX_HTML_EQUATION_'.$i_mathml.'_', $html);
$nodesMathEquation['PHPDOCX_HTML_EQUATION_'.$i_mathml.'_'] = $equation;
