Time tooltips not disappear when touchend on mobile phone

[jinaviva]

Videojs-sprite-thumbnails is a pretty repo, and can be displayed very well on mobile phones after updating video.js 8.20.0 . But I found a small problem.That is, on mobile phones use andriod and chrome, when the user touches slidding progress seekbar , the time tooltips and sprite-thumbnails displayed normally, but when user touch end,the time tooltips and sprite-thumbnails will not disappear automatically. The user needs to click elsewhere on the screen to make them disappear. I've tried everything and can't find an elegant solution.I don’t know if it is a problem with my program or a bug in video.js.

@jinaviva I noticed that too, and it's not an issue with your setup.

In my opinion this can be solved with 1 additional CSS rule. I submitted a pull request here.
