Error in plotly express scatter with continuous_color_scale and marginal_x

Hello

i am logging this as i think this might be a bug. I found while building a Dash app but the same issue arises in a a jupyter notebook.

import plotly.express as px
df = px.data.iris()

below, it works as expected:

fig = px.scatter(df, x="sepal_width", y="sepal_length", color="sepal_length",color_continuous_scale='Viridis')
fig

so is the following

fig = px.scatter(df, x="sepal_width", y="sepal_length", color="sepal_length",marginal_x='box')
fig

But the following expression breaks down

fig = px.scatter(df, x="sepal_width", y="sepal_length", color="sepal_length",marginal_x='box',color_continuous_scale='Viridis')
fig

it looks like box marker is using 'V' of Viridis in the color_continuous_scale.

Thanks

首先，在 Jupyter notebook 中运行提供的 Python 示例，并将可正常工作的情况与 marginal_x='box' 和 color_continuous_scale='Viridis' 的组合进行比较。跟踪该组合如何构建 scatter 和 marginal box traces；完成标准是图表能够渲染，且不会使用连续色阶中的错误颜色显示 box marker。
