Normalized Histogram with Marginal producing the wrong plot

Using plotly.express (px) to plot a Histogram with barnorm = 'percent' and marginal = 'histogram' produces a plot where the barnorm is ignored and the raw counts are plotted. I think the output should be a histogram with barnorm = 'percent' and a marginal histogram with the regular counts.

px.histogram(pd.DataFrame({'x': np.random.normal(0, 1, 100),
                           'col': np.random.choice(['A', 'B'], 100)}), 
             x='x', color='col', barnorm='percent', marginal='histogram')

首先运行提供的 plotly.express 直方图示例，并将主直方图与其边缘直方图进行比较。跟踪 plotly.express 的直方图路径，以确定 barnorm 在哪里应用，然后验证主图使用百分比归一化，而边缘直方图保留原始计数。
