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).

首先运行提供的 Python MWE，并在 subplot 图中切换 option1 和 option2 按钮。检查隐藏 traces 时共享的 x 轴条目是如何保留的，以及这些选项共享标签 B 时的情况。完成标准是：切换到 option2 后，不再显示 option1 遗留的 C x 轴条目。
