Maybe I can also add another question. I'm trying to enable multiple brushed regions on a plot that is linked. So for example brush one area, then brush another area, maybe with a different highlight color. Is this possible?

and the package versions are I guess the latest

#
pytest-selenium 1.6.0 py_1 bokeh
selenium 3.4.3 py36_0 conda-forge

It's possible something about the newer selenium is currently incompatible. My first suggestion is to downgrade selenium to the version above and see if that works,

Thanks,

Bryan
