Error bars in px.scatter should inherit color and opacity from markers by default

Error bars do correctly show with the same color (not opacity) as markers when using categorical data to set the color parameter:

import plotly.express as px
df = px.data.iris()
df["e_plus"] = df["sepal_width"]/100
df["e_minus"] = df["sepal_width"]/40
fig = px.scatter(df, x="sepal_width", y="sepal_length", color="species",
                 error_y="e_plus", error_y_minus="e_minus")

fig.show()

However, setting the opacity parameter only changes the opacity of the markers:

fig = px.scatter(df, x="sepal_width", y="sepal_length", color="species",
                 error_y="e_plus", error_y_minus="e_minus", opacity=0.6)

fig.show()

And using numerical data to set the color parameter, the error bars will not have the same color as the markers, but instead renders in black:

fig = px.scatter(df, x="sepal_width", y="sepal_length", color="petal_width",
                 error_y="e_plus", error_y_minus="e_minus")

fig.show()

Fixing this would be super helpful, since the only current solution seems to be to manually add or update the trace for every single data point to set rgba-values for the error bars. My scatter plot had a few thousand data points, making that a very time consuming for-loop.

Comece com as reproduções fornecidas de px.scatter usando valores de cor categóricos e numéricos, com e sem opacidade. Inspecione as configurações geradas das barras de erro e dos marcadores para identificar onde a cor e a opacidade deles divergem. Considera-se concluído quando as barras de erro herdarem, por padrão, a cor e a opacidade do marcador em todos os casos mostrados, com cobertura para as reproduções.
