ass subtitle style parameter: xscale, yscale

Just jumped from the latest version on cydia (15.2-1) to 16.x and noticed ASS styles are working now. However my xscale and yscale parameters aren’t being honored. The reason they’re there is to compensate for my anamorphic videos scaling (720×480 to 4:3). It’d be cool if these were supported too in the future Theyre an optional setting for the ASS style header that applies globally, not the individual line settings.
