ItPro.TV Course Library Extremely Sluggish Topic is solved

[Channel 2012]

I've never seen a website behave like this in Pale Moon before. Trying to browse the course library on the ItPro.TV website leads to extremely high processor utilization and sometimes "unresponsive script" errors (especially on my slower computers). I've replicated this issue on three different systems running the latest version of Pale Moon (all 64bit) and confirmed that the problem is not present when viewing the site with Internet Explorer.

I have tried starting Pale Moon in its "Safe Mode" with no change. I've also reached out to the website support team and have informed them of the issue, assuming that it is on their end. In the meantime, is there any kind of workaround short of just browsing that site with IE?
