After %blockrun <button>, notebook jumps to bottom about ipython_blocking

[kafonek]

thanks for the kind words @rlele5 . I'm not very familiar with how the front-end javascript of Notebook classic works, I think linking this issue and bringing up the topic in something like https://gitter.im/jupyter/jupyter or stackoverflow is your best hope on getting a definitive answer. My general understanding is that the front-end javascript automatically scrolls to each cell as it's executed.

From the front-end's perspective, %blockrun doesn't stop cell execution. The code in each cell is indeed sent over websocket to the jupyter server just like code execution without ipython_blocking involved. It's just that the actual execution of that code is deferred until the blocking action (widget change or whatever) is complete. Then all the deferred code is executed and the output of each cell is filled out.

In summary, it might be possible to have the UI jump back to the cell where %blockrun or the widget target of blockrun is defined. I just don't know how to do it.
