rangeslider doesn't update if range is changed using array

[jdugge]

If the range of a plot with a rangeslider is changed using Plotly.relayout(gd, {'xaxis.range': [3,9]}); or Plotly.relayout(gd, 'xaxis.range', [3,9]);, the rangeslider doesn't update to reflect the changed range.

However, when using Plotly.relayout(gd, {'xaxis.range[0]': 3, 'xaxis.range[1]': 9});, both the main plot and the rangeslider get updated correctly.

Reproducible example on codepen

Interesting bug. This is likely to do with this section - the way updates are handled as strings is very imperfect at the moment and could benefit from some work to make it more robust and generalized (hopefully using Lib.objectFromPath.

Thanks for reporting though and we'll likely have a fix later this week for the next release.
