[whatwg] Timing for the poster image appearing for <video>

[Adele Peterson]

Hi all,

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.  I think it would make more sense to just allow the poster  
image to be displayed if the readyState is less than CAN_PLAY, instead  
of considering the paused state.  The paused state will always be true  
when the readyState is less than CAN_PLAY, but with this rule, the  
poster image won't randomly show up in other situations where the  
video is paused and you're at the beginning.

Thanks,
	Adele
