High CPU/GPU utilisation at "Buy Now" Page

At the subpage “Buy Now” (currently https://lastepoch.com/supporter-packs) the CPU utilisation (without active hardware acceleration) respectively GPU utilisation is “abnormal high”*.

“Abnormal high”* like at Website which are using “hidden cryptocurrency mining” scripts etc (just an example, couldn’t find any here)

As soon as i block those (currently) seven mp4/webm, permanently looping in the background, via Browser dev-tool, i am able to navigate there with the expected “low” hardware utilisation.

Tested on 4 Devices with different specs, Browser and OS (Android, Win 10, Ubuntu)
