Access: [7.1.1.3]: remove flicker (embed)
(Priority 1)

Cause:

Ensure embedded items such as movies, audio files, etc. do not cause on-screen flickering. It can trigger epileptic seizures in people with photosensitive epilepsy. At present, browsers do not allow screen flickering to be disabled by the user.
