Description

[Mohammad Maruf Rahman]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:45.0) Gecko/20100101 Firefox/45.0
Build ID: 20160407164938

Steps to reproduce:

I just went to bbc.com

than choose a page and went to the page

played the video in the page and tried to scroll


Actual results:

When I loaded the page i could see a video in the page. If you watch before playing a video, you can see a still image in the video playing section, because the video is not playing . That is why a image is seen. Then when I play the video, and scroll, I could see that that still image (WHICH CAN BE SEEN BEFORE PLAYING VODEO) comes back again. If I scroll. this problem is seen then


Expected results:

If I scroll or not, the video  should be playing as usual. NO still image should come.
