Marginal plots are not colored/themed as expected

[jnumainville]

Description

Marginal plots are not colored/themed as expected.

Steps to reproduce
Create a plot with marginals

import deephaven.plot.express as dx

stocks = dx.data.stocks()

scatter = dx.scatter(
    stocks, 
    x="Price",
    y="Dollars",
    marginal_x="rug",
    marginal_y="violin"
)

Expected results
Marginals have the same color as the base plot.

Actual results
Marginals have different color(s) than the base plot. It looks like the colors are removed by the client then not added as expected by the colorway.

Additional details and attachments

This can be worked around by manually setting the color

stocks = dx.data.stocks()

scatter = dx.scatter(
    stocks, 
    x="Price",
    y="Dollars",
    marginal_x="rug",
    marginal_y="violin",
    color_discrete_sequence=["salmon"]
)
