hiding lineNumbers on editor not working

[jhefreyzz]

I read codemirror's manual and hopefully it would be working on hyperMD since it work side by side with codemirror

code snippet from docs with lineNumber option (added)

var cm = HyperMD.fromTextArea(myTextarea, {
  /* ...other editor options */

  mode: {
    name: "hypermd",
    lineNumbers: false,
    hashtag: true, // example. enable hashtag
  }
})

It seems not working.

var cm = HyperMD.fromTextArea(myTextarea, {
  /* ...other editor options */
  /* put here */
  lineNumbers: false,
  mode: {
    name: "hypermd",
    hashtag: true, // example. enable hashtag
  }
})
