Mp4 streaming background caching

I am working with owncloud 9.0.3.2.

When I select a mp4 link, video streaming is started in web browser (linux/firefox 47.0). Everything working fine.
If I select the pause button, streaming is stopped. If I select the upper right corner X icon, video disappears.
But video downloading is continued in background until I select the upper left corner Files selection again.

This may be a problem for overall server bandwidth or for people who have volume limited internet access.
How can I change configuration to disable this behaviour (unintended data caching/download of videos in background after closing these videos).

You can directly report this to the bugtracker: https://github.com/owncloud/files_videoplayer/issues
