heatmap: colorbar.showticklabels cannot be set to false (nothing is rendered)

[Nauss]

This pen is simply the basic heatmap example with the showticklabels option set to false.

colorbar: {
  showticklabels: false
}

If I comment the option or set it to true it works correctly.

Looks like a bug or am I missing something ?

Thanks @Nauss - very clearly a bug, it's throwing a JS error.

@alexcjohnson will that showticklabels attribute set to true value ?

Nice, great (and fast) job, thanks !
