 After the upgrade to 4.7, some users
 [https://ru.wordpress.org/support/topic/вп-4-7-и-цп-100x4/ reported a 100%
 CPU load] after being redirected to the About page, apparently caused by
 three videos set to `autoplay="1"` simultaneously. Others made a point
 that it's also a bad UX for users with slow and/or limited data plans.

 We should try to fix it in 4.7.2 or at least avoid doing that for future
 releases.
