Thanks, filed an issue here: https://github.com/ipython/ipython/issues/10702
If you are able to provide me with some high-level guidance on how to
implement this feature in run_cell, I will be more than happy to send a PR
with the changes. For my own use-case, I don't need any changes to
HistoryManager. In fact, I can just store an additional field parallel to
last_execution_succeeded. However, I don't know if this is necessarily the
best long-term option.
Please let me know and thanks again for your help.
