LATEX RENDER ERROR

Can't get Latex or mathjax work in moodle !

1. Because latex not working in moodle , after some google search , I add

scripts.push('https://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS_HTML');

in createScriptTags in ./mod/hvp/library/js/h5p.js , It seems everything is ok now .

2. But when I create several slides in Course Presentation , I found the first two slides render latex ok , but from the third slide on ,

everything goes wrong .

3. Platform : ubuntu18.04.1 LTS moodle3.8.2+(Build:20200402)

5 Browser: Chrome

6 H5P plugin version : 1.20.2 (2020020500)
