plotly.js now prunes unsupported global-level trace attributes

[antoinerg]

Just a heads up that we made some changes to the _fullData and PlotSchema in plotly.js: we now remove some global-level trace attributes that weren't supported at the individual trace level. Discussion about this issue is still going there: plotly/plotly.js#3058. PR plotly/plotly.js#3158 which is now released in v.1.42.1 partially closes the aforementioned issue.

@dmt0 can you take a look at this sometime and see if this causes issues for us?

I imagine percy would tell us if anything would go wrong. But, yes, I'll look around.
