Hi Team,

When more than one video element on the page, playback sound is stopped.
I think settings of the first video is applied to the following ones.

TEST 1 (video 1 muted / video 2 muted): http://sample.teads.net/demo/ts/Demo%20-%20muted%20-%20muted.html
=> OK, the playback sound is not stopped as expected

TEST 2 (video 1 muted / video 2 unmuted): http://sample.teads.net/demo/ts/Demo%20-%20muted%20-%20unmuted.html
=> OK, the playback sound is not stopped as expected

TEST 3 (video 1 unmuted / video 2 muted): http://sample.teads.net/demo/ts/Demo%20-%20unmuted%20-%20muted.html
=> KO, the playback sound is stopped

This issue seems related to https://bugs.webkit.org/show_bug.cgi?id=177920
