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).

if (typeof ImageData !== "undefined" && imgData instanceof ImageData) {
      ctx.putImageData(imgData, 0, 0);
      return;
    }
    
    
    
    
    
    
    
    
    
    
    const height = imgData.height,
      width = imgData.width;
    const partialChunkHeight = height % FULL_CHUNK_HEIGHT;
    const fullChunks = (height - partialChunkHeight) / FULL_CHUNK_HEIGHT;
    const totalChunks = partialChunkHeight === 0 ? fullChunks : fullChunks + 1;
    const chunkImgData = ctx.createImageData(width, FULL_CHUNK_HEIGHT);

      destPos;
