How to trigger Hover(and tooltips) in multiple bokeh figures simultaneously?

I have multiple figures, sharing y-axis but not the x-axis. When my cursor hover on one figure, it will tell me the values (x & y-axis values). But Others have no tooltips. I want all figures show tooltips simultaneously when cursor hover any figure where the CrosshairTool intersect lines.

Below, I posted the sample code that gives me result shown on the left.

Any help is highly appreciated!

import numpy as np

import pandas as pd

from bokeh.plotting import figure, show
from bokeh.layouts import row
from bokeh.models import HoverTool, CrosshairTool, ColumnDataSource, Span

df = pd.DataFrame({
    'depth': np.linspace(1000,1100,201),
    'x1': np.linspace(80,90,201)+np.random.rand(201),
    'x2': np.linspace(2.5,3.5,201)+np.random.rand(201)/10
})

source = ColumnDataSource(df)

p1 = figure(y_range=(df['depth'].max(),df['depth'].min()),
    width=400,height=600,y_axis_label='Depth (m)')

p2 = figure(y_range=p1.y_range,width=400, height=600)

p1.line('x1','depth',source=source, line_width=2, color='blue')
p2.line('x2','depth',source=source, line_width=2, color='green')

hover1 = HoverTool(
    tooltips=[('', '@depth{0.0} m'),('', '@x1{0.0} °C')],
    mode='hline',attachment="above"
)

hover2 = HoverTool(
    tooltips=[('','@depth{0.00} m'),('','@x2{0.00} µs/ft')],
    mode='hline',attachment="above"
)

xspan = Span(dimension="width",line_width=0.5)

p1.add_tools(CrosshairTool(overlay=xspan))
p2.add_tools(CrosshairTool(overlay=xspan))

p1.add_tools(hover1)
p2.add_tools(hover2)

layout = row(p1,p2)

show(layout)
