Reset Toolbar Button not Resetting Slider


I have an issue where when I press the reset button on my toolbar everything resets, except for the slider.

If I change the slider to the settings below (image), the chart changes but if I press the reset toolbar button the slider does not go back to it’s original position

Does anyone know what is going on.
I am running Bokeh 2.1.0
Here is my code for replication.

import numpy as np
import bokeh.plotting as bp
from bokeh.models import CustomJS
from bokeh.models.widgets import DateRangeSlider
from bokeh.layouts import row, widgetbox
from bokeh.plotting import figure, show, output_file

df = pd.DataFrame(np.random.randint(0,30,size=(25, 3)), columns=list('ABC'))
df['date'] = pd.date_range('2021-02-01','2021-02-25') ='Numbers'
dt = bp.ColumnDataSource(df)

xmin = - pd.Timedelta(days=1) # set xmin 
xmax = + pd.Timedelta(days=1) # set xmax  


p = figure(title="Example", 
       x_axis_label = "Number", y_axis_label = "Temperature in C",
       x_range = (xmin, xmax), x_axis_type = 'datetime')

p.line(source=dt, x='date', y='A', color='blue', legend='Line A')

callback = CustomJS(args=dict(p=p), code="""
    var a = cb_obj.value;
    p.x_range.start = a[0];
    p.x_range.end = a[1];

range_slider = DateRangeSlider(start=xmin, 
                      end=xmax,value=(xmin,xmax), step=86400000, title="Test")
range_slider.js_on_change('value', callback)

layout = row(p,widgetbox(range_slider))

@rodrigo The code is behaving exactly as expected. The reset tool does not know anything about any sliders or other widgets. All it does it update the range start/end values and you have not set up any on_change callbacks on those.
