A less popular [drvic10k/bootstrap-sortable](https://github.com/drvic10k/bootstrap-sortable) manages to handles this case in a clever way, using as many duplicates of rowspan cells as needed to keep a table properly formatted: https://jsfiddle.net/jz5tnq4y/15/. ![peek...

When user executes a long-running cell twice it could be: ```python { "pending_requests": [ { # msg_id of an `shell.execute_request` (allowing to identify subsequent "iopub.status" by parent_header "id": "3ec6186d-dbd2-486e-9622-e771b4bdcc21", "type":...

This is not about concurrent executions but queuing. We need to record the queue to resolve the status properly.

To illustrate if I have a cell: ```python from time import sleep sleep(60) ``` I execute it first time, the `pending_requests` would change to ```python [ { "id": "3ec6186d-dbd2-486e-9622-e771b4bdcc21", "type":...

As a counter proposal, https://github.com/jupyter-server/jupyter_ydoc/pull/227 adds `pending_requests`. We already discussed this at length with @davidbrochart but I am still on fence here. I wanted to highlight it here in case...

To recap, we have three proposals: - a) store `pending_requests` in jupyter-server and expose a dedicated REST API to sync it with frontend https://github.com/jupyter-server/jupyter_server/issues/990 - b) store `pending_requests` in the...
