Video embed

Users should have the ability to move focus to a video embed element and play the video using the keyboard.

• The iframe element should use the video title in its title attribute
• The play button text should use the video title, followed by the type of video in parentheses, i.e. "(YouTube video)"
• The thumbnail image should have alt text that describes the image, followed by "(video thumbnail)"
• The YouTube embed should have accurate captions. Autogenerated captions by YouTube are not sufficient
