Colorbar Orientation Change Causes Render Issue

Hello,

I was adding a control to one of my graphs in order to change the colorbar orientation from 'v' to 'h' and back again (user discretion) and noticed that it was having some strange behaviors.

Basically, it renders very strangely on change -- leaving the labels from the previous orientation and skewing things.

I did find that if I turn off the colorbar after changing orientation and turn it back on that it renders correctly.

So, I have created a workaround that onchange of orientation I hide the colorbar, do a plotly.react, then trigger a show of the colorbar and a second plotly.react.

I have demonstrated this in the following codepen: https://codepen.io/dritchie/pen/NWmOrZL

I commented out the 'fix', so both the weird behaviors and the correction can be shown.

Thanks!

Commencez par la reproduction CodePen liée et examinez les appels à plotly.react qui modifient la colorbar orientation entre 'v' et 'h'. Confirmez le comportement avec la colorbar activée, puis vérifiez que la modification de la orientation est rendue sans les libellés de l'orientation précédente ni une mise en page déformée, sans le contournement hide-and-show.
