possible bug dual X axis both on top

I tried creating a figure with 2 different x-axis. It works as long as I set both x_axis_location= “below” OR one x_axis_location set to ‘below’ and one to ‘above’. However , I cannot set both to ‘above’ the plot does not render correctly. Any ideas?

import numpy as np

from bokeh.plotting import figure, show, output_file, hplot

from bokeh.models import LinearAxis, Range1d

N = 100

y = np.linspace(1,101,N)

x =10-np.log(y)

s = np.linspace(30, 35, N)

s[0:10]=np.linspace(10, 30, 10)

yr = Range1d(start=101,end=0)

output_file(“XISSUES.html”)

TOOLS = “pan,wheel_zoom,box_zoom,reset,save,box_select”

p3 = figure(title=“X ABOVE”,y_range=yr, x_range=(0, 10),x_axis_location=“above”, tools=TOOLS)

p3.circle(x, y, legend="Fake Temperature ")

p3.xaxis.axis_line_color =“blue”

p3.xaxis.major_label_text_color = “blue”

p3.extra_x_ranges = {“foo”: Range1d(start=0, end=35)}

p3.circle(s, y, fill_color=“green”, size=5, line_color=“green”, x_range_name=“foo”, legend=“fake Salinity”)

p3.add_layout(LinearAxis(x_range_name=“foo”, axis_line_color=“green”,major_label_text_color=“green”), “above”)

show(p3)
