Empty array axis anchor leads to fatal id.match is not a function error

Minimal example https://codepen.io/cpsievert/pen/QWjzGgJ

Initially reported in plotly/plotly.R#1768

Seems to work if one sets yaaxis2.anchor to free instead of an empty array.
Am I missing something?

[cpsievert]

Ohh, yes, thanks, and sorry for the noise :)

@cpsievert no worries. Please feel free to re-open if you think we should better handle that case of empty array?

Low priority, but a thrown error preventing rendering is a bug even if it resulted from garbage input.
