mouse issue with subtitles popup UI in video player

Not sure if this is the right place to report this.

I noticed the following issue with the new Estuary theme in Kodi v17 (tested on beta 5). Basically when using a mouse its nearly impossible to click on the Download button. After hovering over the subtitles icon the popup comes up but as soon as you move the mouse up to hit Download the popup starts disappearing, unless you accidentally hit Download button quickly before the popup goes away you can click it, but its an 1 in 50 tries thing.
