Also here with comments :/

Same on the Ubuntu 20.04, installed via Snap

Install virtualenv then do ``` virtualenv -p python3.6 venv source venv/bin/activate ``` And then do the installation instructions

Please provide updates will this be merged to master ?

you need to exclude `wp-includes/js/dist` folder and `js/jquery/jquery.js` file from defer loading via `data-pagespeed-no-defer` attribute.

Second option: first the PageSpeed rewritten file then the original file.

https://strongboxtechnology.10web.cloud/ here is the website, as you can see it loads `wp-content/cache/tw_optimize/js/two_07f45a878040049d26642d9ad2754c36.js.pagespeed.jm.jNGuvHpZaz.js` and `wp-content/cache/tw_optimize/js/two_07f45a878040049d26642d9ad2754c36.js`. If you open https://strongboxtechnology.10web.cloud/?PageSpeed=off you'll see that there is only one load of that file.

 But there is no preloaded js with disabled PageSpeed module.

There is something wrong with `hint_preload_subresource` the issue is gone when I disable that filter

Yep, I also think so
