The latter option no longer appears to be valid, yielding a `ValueError`. For example, the following does not work in (tested in a Jupyter notebook):

```
import plotly.graph_objs as go

data = [
    {
        'y': [1,2,3],
        'line': {
            'dash': '5px,10px,2px,2px',
        }
    }
]
go.FigureWidget(data)
```
Specifying dash length list no longer works

Hi @username_0 , thanks for the report!

I just opened an associated issue on the Plotly.js project to work out how we should handle this case. Check it out if you're interested in what went wronge here: https://github.com/plotly/plotly.js/issues/2903

Ok, looks like we'll handle this by introducing a custom `LineDash` validator class.
