Block automatic fullscreen on these sites

For security reasons, the
requestFullscreen() web API
requires a prior user gesture ("transient activation") to be called or will
otherwise fail. Users' personal settings may allow certain origins to call
this API without a prior user gesture, as described in
https://chromestatus.com/feature/6218822004768768.

This policy supersedes users' personal settings and blocks matching origins
from calling the API without a prior user gesture.

For detailed information on valid url patterns, please see
https://chromeenterprise.google/policies/url-patterns.
Wildcards, *, are allowed.

Origins matching both blocked and allowed policy patterns will be blocked.
Origins not specified by policy nor user settings will require a prior user
gesture to call this API.
