Crash Tab Issue by Specific YouTube Video
I use Vivaldi snapshot 1.5.609.8 on macOS Sierra 10.12. When I watched a video of YouTube playlist, Vivaldi's tab was crashed at the same time that a video was finished. [img size=500]http://art33.photozou.jp/pub/201/124201/photo/241217816_org.v1474569692.png[/img]
I made a mistake. Vivaldi's tab on macOS Sierra doesn't crash by YouTube playlist. Vivaldi's tab crash by specific YouTube video. So, I changed this topics title. When these YouTube videos finished to play, Vivaldi's tabs crashed!

I think the reason of this issue is Chromium. Because this issue was happened on Opera 40.0 on macOS Sierra, too. But this issue was not happened on Firefox 49.0 and Safari 10.0.
The above YouTube videos were not crashed by using Flash Player. So, I watch YouTube video by using the extension "Disable Youtube HTML5 Player".

And Vivaldi 1.5.609.8 on macOS Sierra always crashed by that Twitter video finished to play. So, I think this issue is connected with macOS and HTML 5 video.
I confirmed this issue was happened on the Vimeo movie.
And Vivaldi's staff, Ruarí Ødegaard said about this issue on Twitter. He said,
"Hey, we noticed that our Mac fans on 10.12 Sierra are getting some crashes with videos. We are testing a possible fix."
"The crashing videos on macOS Sierra 10.12 has now been resolved in a 1.4 minor update"
I confirmed this issue was fixed on Vivaldi snapshot 1.5.618.8. Thank you!
