Dev edition: web worker doc example typo, nesting canvas elements

[susan51531]

Page: Using a JavaScript module as a worker

This code example appends a canvas to the existing canvas#output, which is not valid. Maybe replace canvas#output to div#output, or reusing canvas#output to paint the image without creating a new one every time.

-<canvas id="output"></canvas>
+<div id="output"></div>

Ah, yeah, this is a great find! I think in addition to the change you mention, we'd want to change output.appendChild(canvas) to output.replaceChildren(canvas).

A pull request fixing this would be welcome!
