Description

Using aggregate=False in esm_datastore.to_dataset_dict() triggers a deepcopy of the object. For whatever reason, the deepcopy forgets any manual changes made to the dataframe by updating cat.esmcat._df (e.g. as recommended in the documentation here). I would expect manual changes made to the dataframe to be cascaded through the rest of the object.

What I Did

Replicate the tutorial here: https://intake-esm.readthedocs.io/en/latest/how-to/manipulate-catalog.html

Only change made was to add aggregate=False in the call tocat_subset.to_dataset_dict().

Now all 40 original assets are loaded instead of just the 8 intended assets after cat_subset.esmcat._df was modified.

I'm also encountering this issue, any chance this has been fixed already?
