print doesn't work in any event handler

[MaxDesiatov]

While using print as a top-level invocation works, if you call print in any closure handler, such as onclick, addEventListener etc, print output is not redirected to console.log. Apparently, there isn't anything that reads from stdout and redirects to console.log at that point.

Hmm, I couldn't reproduce. How do you redirect stdout? Could you try that way used in IntegratedTests?

const wasmFs = new WasmFs();
// Output stdout and stderr to console
const originalWriteSync = wasmFs.fs.writeSync;
wasmFs.fs.writeSync = (fd, buffer, offset, length, position) => {
  const text = new TextDecoder("utf-8").decode(buffer);
  switch (fd) {
  case 1:
    console.log(text);
    break;
  case 2:
    console.error(text);
    break;
  }
  return originalWriteSync(fd, buffer, offset, length, position);
};

This is great, thanks! Would you mind if I create a PR that adds this to index.js in the example?

Thanks. It would be helpful 🙏
