The ratio will broken when play vertical direction video by HLS using IE 10
As title, I play the vertical direction video by HLS.
Only when I use IE 10( jwplayer play the video by flash) the ratio is broken.
But when I play the video by Chrome, Firefox, Edge and IE11 the ratio is correct.
Is this a bug?
OS: window 10
