vimeo.com/event/{id} (and /event/{id}/{hash} for unlisted events) now get
the same click-to-play card as Vimeo videos, embedding Vimeo's live-event
player (vimeo.com/event/{id}/embed[/{hash}], dnt=1). The issue assumed
this needed vimeo.com in the CSP, but frame-src is already https: on web
and desktop.
