Compatibility with javascript delaying option in Easy Optimizer

Hello. I am running Tutor LMS on a site with Woocommerce and the Easy Optimizer plugin. In Easy Optimizer I enabled Javascript delaying with the Defer (native browser) method so as to maximize compatibility.

However one issue that showed up is that with a course that had a video embed, the loading spinner showed up and never went away. The video embed loaded behind the spinner but the spinner itself was broken. I know this is a problem with the optimization and I have posted to their support forums, however I would like to report this here as well since I guess it’s common for people to use optimization plugins and I know that optimizations should be tested thoroughly, but I found it odd that this specific situation happened. I may be wrong but I am under the impression that Tutor LMS would at least be somewhat compatible with some optimization techniques.

I tried adding the course pages to Easy Optimizer’s exclusion settings but that didn’t work, so I reported this to them as well. Still, I feel this spinner thing may be a bug in Tutor, as everything else on the site works just fine with javascript delayed.

And again: I set it up to delay via browser methods and *not* to delay until first interaction (as I am aware this would actually break too many other things, including the spinner).
