const worker = workerize(`
        export function drawImage(canvas,image){ return canvas.getContext("2d").drawImage(image, 0, 0)}
         `)(canvas, image)
worker.drawImage(document.querySelector('canvas'). transferControlToOffscreen(),img)

it will throw

DOMException: Failed to execute 'postMessage' on 'Worker': An OffscreenCanvas could not be cloned because it was not transferred.

i am also interested in this, because i'd like to workerize the webp-hero polyfill, which will best be implemented with a transferable OffscreenCanvas
