Details

Steps to reproduce:

  1. open https://doc.rust-lang.org/std/iter/trait.Iterator.html
  2. see the CPU usage and wait until the loading finishes

Expected result:
It should finish shortly.

Actual result:
It takes minutes to load which is way too long...

Based on profile I believe it's mainly in JavaScript engine somehow interact badly with the page's script.
