Block automatic full screen on specified sites

For security reasons, the
requestFullscreen() web API
requires a prior user gesture ("transient activation") to be called or it
fails. Users' personal settings can allow certain origins to call this API
without a prior user gesture.

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

For detailed information about valid URL patterns, see https://go.microsoft.com/fwlink/?linkid=2095322.
Wildcards (*) are allowed.

Origins matching both blocked and allowed policy patterns are blocked.
Origins not specified by policy or user settings require a prior user
gesture to call this API.
