Alternate title: _Applying #6684-similar fix to stroke_
#6684 makes sure the "current" transformation, at the moment of filling radial gradients is the `baseTransform` (that of the rescource (page), as it says in the specs). However, this should also be fixed in [`CanvasGraphics_stroke`](https://github.com/dsprenkels/pdf.js/blob/a9081653fc565eb72c3eb5142c17088cb162e7ce/src/display/canvas.js#L1052).

      const ctx = this.ctx;
      this.save();
      
      ctx.scale(1 / width, -1 / height);
      const currentTransform = ctx.mozCurrentTransformInverse;
      let widthScale = Math.max(
        Math.hypot(currentTransform[0], currentTransform[1]),
        1
      );
      let heightScale = Math.max(
        Math.hypot(currentTransform[2], currentTransform[3]),
        1
      );
