Changing active slider value doesn't change the displayed data

How can I change the displayed data subset when using animation_frame? fig.update_layout(sliders=[dict(active=...)]), shown in the docs, only changes the value selected on the slider itself, but not the actual data. In this example, it's still showing the data associated with z=1 (notebook).

import plotly.express as px
import pandas as pd

df = pd.DataFrame(dict(x=[0, 1, 0, 1],
                       y=[0, 1, 1, 0],
                       z=[0, 0, 1, 1]))

fig = px.line(df, "x", "y", animation_frame="z")
fig.update_layout(sliders=[dict(active=1)])
fig.show()

从使用 Plotly Express animation_frame 和 fig.update_layout(sliders=[dict(active=1)]) 的已报告 Python 示例开始，然后将滑块选择与链接 notebook 中显示的数据进行比较。重现不匹配问题，并跟踪动画帧和滑块状态的处理方式；完成的标准是更改活动滑块后显示相应的数据子集。
