Plotly.react sequence and subplot bgcolor

[nicolaskruchten]

The following Pen shows a simple pair of calls to Plotly.react which causes the plot_bgcolor to be applied to the gridlines of one of the subplots instead of its background: https://codepen.io/nicolaskruchten/pen/QmQXMK

Alright, this one isn't as bad as it looks... the grid actually is supposed to be this color (which is a slightly darkened version of the red background), since we blend plot_bgcolor with the default line color in order to avoid unnecessary opacity. The problem is just that we're not creating the right background rect for the new subplot.

And yes, happens with relayout as well:

Plotly.newPlot(gd,
  [{x:[1],y:[2]},{x:[3],y:[4],xaxis:'x2',yaxis:'y2'}],
  {xaxis2:{overlaying:'x'},yaxis2:{overlaying:'y'},plot_bgcolor:'red'}
)
Plotly.relayout(gd,{
  'xaxis.domain':[0, 0.4],
  'xaxis2.domain':[0.6,1],
  'xaxis2.overlaying':null
})
