SVG bug in Firefox (close banner X icon)
there is a bug in firefox which prevents inline SVG in <img src> from being rendered, when there is an unescaped # symbol, see
https://jsfiddle.net/m1x56s7o/ vs https://jsfiddle.net/m1x56s7o/2/, firefox cannot render the first image in first link.
However, this method of inline svg is used for displaying closing icon for overlay banners in JW Player. That means Firefox users cannot see the icon.
Please, fix this by encoding the source (or at least the # symbols) in inline svg.
