Thank you very much, Bryan, for spotting this. I'm using the push_session functionality and did not know of this shortcoming.
I used it for convenience reasons and will migrate my code to be an app. Maybe it makes sense to emphasize this more in the current documentation as I did read the shortcomings but for my case they were irrelevant.
Thanks again,
Alexander

Are you running the app like:
bokeh serve app.py
Or are you using bokeh.client and push_session? If the latter case, then there is a known issue:
screen distance spec fields fail with bokeh.client · Issue #6409 · bokeh/bokeh · GitHub
Apart from this issue, there are a number of intrinsic drawbacks to using bokeh.client, and always will be. I always advise people to not consider that approach unless there is a clearly identified need (of which I can only think of a handful of very specific ones). It' very nearly always better to write a bokeh app that runs in the bokeh server, either by embedding the Bokeh server programmatically, or by executing "bokeh serve app.py" on the command line.
Thanks,
Bryan
