New description:
Upon 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
[source:tags/4.7.1/src/wp-admin/about.php?marks=90,107,122#L84 three
videos set to autoplay simultaneously]. Others made a point that it's also
a bad UX for users with slow and/or limited mobile data plans.
We should try to fix it in 4.7.2 or at least avoid doing that for future
releases.
