marginal-distribution subplots include overall-trendline

When creating a scatter plot with marginal distributions and an overall trendline (but not trace trendline), the trendline is shown on all three subplots instead of only the main one.
See related StackOverflow question with suggested workarounds.
Repro code:

import numpy as np
import pandas as pd
import plotly.io as pio
import plotly.express as px

pio.renderers.default = "browser"

np.random.seed(42)
data = pd.DataFrame(np.random.randint(0, 100, (100, 4)), columns=["feature1", "feature2", "feature3", "feature4"])
data["label"] = np.random.choice(list("ABC"), 100)
data["is_outlier"] = np.random.choice([True, False], 100)

fig = px.scatter(
    data, x="feature1", y="feature2",
    color="label", symbol="is_outlier", symbol_map={True: "x", False: "circle"},
    log_x=False, marginal_x="box",
    log_y=False, marginal_y="box",
    trendline="ols", trendline_scope="overall", trendline_color_override='black',
    trendline_options=dict(log_x=False, log_y=False),
)
fig.show()

从 px.scatter 入口开始，使用 marginal_x、marginal_y 和 trendline_scope="overall" 运行提供的复现。跟踪整体趋势线如何被分配到边际子图，然后根据该示例添加回归测试；完成标准是趋势线仅出现在主子图上，而边际分布保持不变。
