go.Table creates an unsightly and non-removable scroll bar when plotting on another figure.

When adding a small go.Table trace to a go.Figure object, the renderer creates a scrollbar which cannot be removed or hidden. This scrollbar is of low opacity, but is nonetheless noticable and ruins the professionalism of a graph upon which it is drawn. This is particularly apparent on dark backgrounds, and makes it impractical to place a go.Table in, for example, the upper left corner of a figure for displaying of additional information. Reproducible example and screenshot are provided.

import plotly.express as px
import plotly.graph_objects as go

# Load example dataset
df = px.data.iris()

# Create scatter plot
fig = px.scatter(df, x="sepal_width", y="sepal_length", color="species")

# Set plot background color
fig.update_layout(
    plot_bgcolor="rgb(40, 40, 40)",
    paper_bgcolor="rgb(40, 40, 40)",
)

# Create table trace
table_trace = go.Table(
    header=dict(
        values=["Species", "Sepal Width", "Sepal Length"],
        fill_color="rgba(0,0,0,0)",
        align="left",
    ),
    cells=dict(
        values=[
            df.species[:5],
            df.sepal_width[:5],
            df.sepal_length[:5],
        ],
        fill_color="rgba(0,0,0,0)",
        align="left",
    ),
)

# Add table trace to the top left third of the plot area
fig.add_trace(
    table_trace
)
fig.update_traces(
    selector=dict(type='table'),
    domain=dict(x=[0., 0.3], y=[0.8, 1])
)

# Show plot
fig.show()

首先运行 plotly.py 中提供的 Python 复现代码，并检查 renderer 如何处理放置在另一个 figure 内的 go.Table trace。将结果与截图进行比较，然后验证表格能够占据指定的 domain，且不会显示可见的、不需要的滚动条。
