The spec currently states that the poster image specified in the poster
attribute for <video> can show up either when no video data is available
or when a video element is paused and the current playback position is
the first frame of video.
The second situation seems like it would allow the poster image to be
displayed when a user rewinds the video back to the beginning while
paused.
Looking at the way YouTube videos work when they're not set to autoplay,
the poster frame is displayed up until the video begins playing for the
first time. After that, it always displays whatever frame it's paused
on, until it reaches the end and displays related videos instead.
