Active tools not working with created toolbar

When creating the toolbar explicitly, setting an active tool on the toolbar doesn’t work, but only when setting it on the figure. Is this a bug? Thanks.

from bokeh.plotting import figure, show, output_notebook
from bokeh.models.tools import Toolbar, WheelZoomTool
output_notebook()

wheel_tool = WheelZoomTool()

# Active tools set here don't work
toolbar = Toolbar(tools=[wheel_tool], active_scroll=wheel_tool)
p = figure(toolbar=toolbar, tools='')
# This works fine
# toolbar = Toolbar(tools=[wheel_tool])
# p = figure(toolbar=toolbar, tools='', active_scroll=wheel_tool)
# This also works fine
# p = figure(tools=[wheel_tool], active_scroll=wheel_tool)

p.scatter([1, 2, 3], [1, 2, 3])

show(p)

This looks like a bug. Setting toolbar and tools simultaneously doesn’t make sense and shouldn’t be allowed. figure(toolbar=toolbar) should take the toolbar verbatim.
