Notebook inline display with .app

Hi,

Puzzled about this behaviour… Not sure if the example obsolete, or if it’s my system setup:

user_guide/Deploying_Bokeh_Apps.ipynb the server examples, poping new browser windows work as expected, but the .app() example just displays the server repr.

Inlining, I am assuming without a seperate server , does work as expected. Screenshot below. (jupyter server is running at localhost:8888 as default)

Kind regards
