Hoversubplots=axis not working with make_subplots

Initially reported on the Plotly forum.

Using make_subplots means that the hoversubplots=“axis” will not work correctly.

Sample code that produces the error:
Codepen.

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

df = data.stocks()


fig = make_subplots(rows=3, cols=1, shared_xaxes=True, vertical_spacing=0.03)
layout = dict(
    hoversubplots="axis",
    title="Stock Price Changes",
    hovermode="x",
    grid=dict(rows=3, columns=1),
)

fig.add_trace(go.Scatter(x=df["date"], y=df["AAPL"], name="Apple"), row=1, col=1)
fig.add_trace(go.Scatter(x=df["date"], y=df["GOOG"], name="Google"), row=2, col=1)
fig.add_trace(go.Scatter(x=df["date"], y=df["AMZN"], name="Amazon"), row=3, col=1)
fig.update_layout(layout)
fig.show()

Expected behavior should be the same as when using the Plotly docs hover on subplots example, where hover labels appear for all charts:
Codepen.

首先使用 make_subplots 和 hoversubplots="axis" 布局复现提供的 Python 示例，然后将其与链接的 Plotly 文档示例进行比较。跟踪子图坐标轴和 hover 设置的生成方式；当所有图表都如预期示例所示显示 hover 标签时，即表示完成。
