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!

从链接的 CodePen 复现开始，检查在 'v' 和 'h' 之间更改 colorbar orientation 的 plotly.react 调用。在启用 colorbar 的情况下确认其行为，然后验证更改 orientation 时能够正常渲染，不会出现之前 orientation 的标签或布局倾斜，并且不使用 hide-and-show workaround。
