Scale on small devices are increasing size instead of decreasing

When the width is set and card opened on mobile device in interactive mode the card image take a LOT of space.
Basically

@options.width / baseWidth

when baseWidth e.g. clientWidth is lesser than card width the scale will be larger than 1.
And i guess it should be vice versa e.g.
baseWidth / @options.width
