I recently updated from plotly 1.41 to 1.42.1 in order to get some bug fixes. With the same data, plotting is now going unresponsive. I have two links below showing the same data in two versions of plotly where one hangs.
I'm using Chrome 70.0.3538.67 (Official Build) (64-bit)

Here's 1.42.1:

Here's 1.41.0:

Can anyone determine something wrong with my data or explain why plotly is hanging?

Thanks
