Bug: leftover xaxis entries when toggling between buttons

Minimum Working Example (MWE):

import plotly.graph_objects as go
from plotly.subplots import make_subplots

# Data
option1_x = ['A', 'B', 'C']
option1_y1 = [1, 3, 2]
option1_y2 = [2, 4, 3]

option2_x = ['B', 'D', 'E']
option2_y1 = [2, 1, 4]
option2_y2 = [3, 2, 5]

# Create subplots
fig = make_subplots(rows=2, cols=1, shared_xaxes=True, subplot_titles=("y1", "y2"))

# Add traces for option1
fig.add_trace(go.Bar(x=option1_x, y=option1_y1, name="option1_y1"), row=1, col=1)
fig.add_trace(go.Bar(x=option1_x, y=option1_y2, name="option1_y2"), row=2, col=1)

# Add traces for option2
fig.add_trace(go.Bar(x=option2_x, y=option2_y1, name="option2_y1"), row=1, col=1)
fig.add_trace(go.Bar(x=option2_x, y=option2_y2, name="option2_y2"), row=2, col=1)

# Initially set option1 visible and option2 invisible
for trace in fig.data:
    trace.visible = False
fig.data[0].visible = True  # y1 option1
fig.data[1].visible = True  # y2 option1

# Add buttons
fig.update_layout(
    updatemenus=[
        {
            "type": "buttons",
            "buttons": [
                {
                    "label": "option1",
                    "method": "update",
                    "args": [
                        {"visible": [True, True, False, False]},  # Show only option1 traces
                    ]
                },
                {
                    "label": "option2",
                    "method": "update",
                    "args": [
                        {"visible": [False, False, True, True]},  # Show only option2 traces
                    ]
                }
            ],
            "showactive": True,
        }
    ],
)

fig.show()

Toggling to option2, we can see the C xaxis entry (from option1) still showing (even with no data for it):

This seems to only be an issue with subplots, and when the traces of different options have some xaxis labels in common (in this case B).

提供された Python MWE を実行し、subplot figure 内の option1 ボタンと option2 ボタンを切り替えることから始めます。traces が非表示になったときに共有 x 軸エントリがどのように保持されるか、また option1 と option2 がラベル B を共有している場合にどうなるかを確認します。option2 に切り替えたとき、option1 の残りの C x 軸エントリが表示されなくなれば完了です。
